State Council Environmental Inspectors in Ganzhou Stimulates Tungsten Price

Tungsten products completely rose up since last week. It has lasted for over 10 days. Due to the acceptance and drive of tungsten raw material enterprise, jump in tungsten price appears unexpected, especially tungsten concentrate and APT. There are no prompt goods in the market at present. Quotation of APT is in a chaos due to the lack of tungsten concentrate and disorder of market.

The price of tungsten concentrate is approximately 70,000.00RMB/ton, APT is 110,000.00RMB/ton. However, small deal under high price is not representative, the whole market transition is negative. The sudden rising in price makes down stream enterprise confused and hesitate to buy.

Coincidentally, APT price in European market also rebounds. The quoted price is 180~190USD/ton, which rises about 5 dollars compared to last week. Price of ferro tungsten is around 24.3~25USD/ton, which rises about 0.15 dollars. Europe should be in its summer break, the price is intended to be stable. The flowing of the price this time is completely affected by China market.

APT and Environmental Protection

Another important factor is that state council environmental inspectors settled in Ganzhou last week forces some small APT metallurgy factory to shut down and rectification due to its unqualified environmental protection problems. It may last for one week or even a month. This causes the tungsten market even worse which it has already stays in a situation that manufacturers being reluctant to sell which causes lack of raw material in the market. The supply is getting more nervous and price rises even higher. It is obvious that environmental protection principle has already been an important theory that should be complied in every industry.

The poor demanding has always been the block for rise of tungsten price. However, the markup at present is the main trend. Although there may be risk, it is the challenge and opportunity as well.

Will Apple be Next Nokia?

On July 7, Counterpoint Technology, a market research institute, released its research about smart phone market share of May. It showed that Apple only accounts for 10.8%, which is 1.2% decrease compared with May, 2015 and fell to fifth. On the contrast, China domestic smart phones, the four largest brands, Huawei, Vivo, Oppo and Xiaomi, have been increasing and the percentage is 53%. Among the data, Huawei ranked first with 17.3%, and Oppo 11% with a double going up.

Time goes back. In April, Apple released last quarter financial report. iPhone sales volume had declined as the first time in its sales history. So is its revenue, which is going down 13%, and 33% compared with the first quarter in 2015. After that, Apple promotes its iPhone SE with lower value of USD500.00, in order to interest the small screen users. No doubt, this type of iPhone has been the most obscure products of Apple these years. With a respect, it may run into the rural market. However, it may still lose with the competition of Vivo and Oppo. Even Citibank has lowered down its expectation of the third and fourth quarter financial report, and predicts that iPhone change time will last 30 to 36 months.

tungsten crucible and sapphire screen

After those not so good reports of Apple, will it be next Nokia? It may and may not. If iPhone can effectively grasp the chance of phone change time and increase its quality, including its broken sapphire screen, which is growing in tungsten crucible in thermal field, then it may change its unfavorable situation. Surely, China domestic brands are also improving their quality better and better, so that their competition ability will be stronger. In order to increase their screen quality, the crucible should be pure enough, which is over 99.95%, for assurance of the quality of sapphire. Chinatungsten has been producing tungsten crucible over 20 years, its purity and quality can meet the requirement of producing out high-quality sapphire. Then it could be a power to support the hard ware parts of phones.

WO3 Catalytic Fuel Cell Vehicle Eases Global Warming

Hydrogen fuel cells for its comprehensive advantages of zero-emission, high energy density and conversion rate, long battery life and short time refueling hydrogen ect., is considered to be one of the "best path" for the development of new energy vehicles. With restrictions FCV (Fuel Cell Vehicle) development bottlenecks continue to be resolved, the international leader in the fuel cell technology company's products have been sent to the commercial promotion levels; in the case of cost, over the past 10 years, the production costs of fuel cell system has plummeted with also a certain decline space left; about the support facilities, governments have stepped up efforts to support hydrogen refueling station to relieve the problem in the operation of fuel cell.

fuel cell vehicle
 
The operating principle of hydrogen fuel cell vehicles is that the hydrogen is sent to the fuel cell anode plate (anode), an electron in the hydrogen atom is separated out through the effect of catalyst; then hydrogen ions (protons) which lose electrons will pass through the proton exchange membrane to arrive at the fuel cell cathode plate (positive electrode), while the electron can not pass through the proton exchange membrane, only through an external circuit to reach the cathode plate of the fuel cell, thereby generating a current in the external circuit. After the electrons reach the cathode plate, they will recombine with the hydrogen ions and oxygen atoms to water. Since oxygen supplied to the cathode plate can be obtained from the air, as long as continue to supply hydrogen to the anode plate and the air to the cathode plate with timely water (steam) away, electricity will be continue to be provided. Theoretically, hydrogen fuel cells emit only water, not carbon dioxide, sulfur dioxide, nitrogen dioxide and other products of and the fossil fuels, thus to ease the global warming and improve air quality.
 
The study found that WO3 has a strong corrosion resistance, does not react with almost any acid without the hydrofluoric acid, which is particularly suitable for the high humidity, acidic environment of fuel cell. In addition, the conventional Pt catalyst belongs to precious metal, the addition of WO3 can not only reduce the cost of the catalyst; at the same time, since the WO3 and the metal will produce synergistic catalytic effect which improves the efficiency of the catalyst; in addition, WO3 has the corrosion resistant, as a partial substitute carrier C to longer the life of the catalyst, and also indirectly improve the catalytic efficiency.

 

Defect-Rich Tungsten Trioxide Nanosheet Photocatalyst

Recently, Professor Xiong Yujie of University of Science and Technology of China (USTC), and his group cooperated with a number of the USTC professors to design a class of defect-rich tungsten oxide nanosheet, this kind of new photocatalytic material exhibits excellent aerobic coupled catalytic performance under broad spectrum light conditions, and is expected to achieve low power consumption and low cost of chemical production. It is reported that the defect-rich tungsten trioxide nanosheets have precisely controllable oxygen vacancies, and promote the efficient transfer of photogenerated electrons from the oxide catalyst to oxygen molecules; at the same time, the emergence of defect states significantly broaden the photocatalyst absorbance range to capture solar energy in the wide spectral range of visible and near infrared region. The achievement of Professor Xiong Yujie group achieved effectively capture and conversion of solar energy to pass to solve the bottleneck problem in the oxide catalyst photocatalytic organic synthesis, and make the possibility for the use of solar energy replacing thermal in organic synthesis.
defect-rich tungsten trioxide
Metal oxide (tungsten trioxide ect.) has the advantages of low cost, and exhibits a photocatalytic activity, which is a class of ideal catalytic materials. The key step of semiconductor photocatalysis is in the photocatalyst excitation, the migration of photo-generated electrons and holes, the recombination of electrons and holes in the catalyst or on the surface. Low quantum efficiency of photocatalytic reaction is the most critical factor which makes the photocatalyst difficult to practical use. The core of Professor Xiong yuJie group developed defect-rich tungsten trioxide photocatalyst nanosheet lies in how to reduce cost of catalyst material and improve the efficiency of energy conversion.
 
At present, doping or semiconductor composite is usually used to reduce costs and to improve catalytic efficiency of tungsten trioxide photocatalyst, such as tungsten trioxide as a carrier after loading the precious metals (e.g. Pt, Au, etc.), it will show strong oxidizing in the presence of water and oxygen thus to help organic synthesis with high reactivity; titanium dioxide and tungsten trioxide complex semiconductor to improve the photocatalytic activity.

 

"Made In China 2025" Promotes the Development of Tungsten Heater

As the first decade guideline of "three-step" strategy for construction of manufacturing power of China, "Made In China 2025" depicts a path for Chinese manufacturing from large to strong, which has been gained high-level attention by Communist Party of China (CPC). In early July 2015, the State Council set up national manufacturing power construction leading group, and the vice-premier Ma Kai is the group leader, and there are more than 20 government departments involved in this group. This group has held the third meeting and established a consultative committee for construction strategy of national manufacturing power, and builds up intersectoral links joint-action mechanism and actively mobilizes multi-power and enthusiasm.

Over the past year, for the implementation of the "Made in China 2025", the government mainly carried out three aspects. Firstly, the government prepared and issued the "1 + X" plan. Secondly, the government formulated a number of supporting policies. CBRC revised the "Commercial Bank M & A Loan Risk Management Guidelines" to encourage the support of commercial banks to manufacturing concern. It would work with the Ministry of Industry and Information Technology of the People’s Republic of China to further improve the financing guarantee system. The introduction of these supporting policies, mainly in order to provide the reasonable support for necessary innovation and development for manufacturing.

The third is to strengthen the guidance of local, promote development of regional differences. Some effects and implementation of policies and the major projects has been initially apparent. For example, “Enterprise R & D Expenses Plus Deduction Policy” further stimulates industrial enterprises, especially SMEs (Small and Medium Enterprises) innovation and dynamic development. Future development of "Made in China 2025" will be more perfect, be more conducive to long-term development of business volume, so that it will greatly facilitate the tungsten heater and other tungsten enterprises development.

WO3 May Be Catalyst of Black Tech Fuel Cell

SOFC systemRecently, Nissan release the automobile solid oxide fuel cell (SOFC): vehicles which equipped with solid oxide fuel cells will use bio-ethanol rather than the liquid hydrogen. Produce ethanol reformer hydrogen combines with oxygen in the air in a fuel cell to produce electricity, then discharging water. According to the source, this system is more efficient than the existing hydrogen fuel cell system, which the recharge mileage can reach about 600 km. what kind of black tech is SOFC?SOFC is the third generation of the fuel cell, a solid-state chemical mean which direct converted efficiently and environmentally friendly the chemical energy which is stored in the fuel and oxidizer to electric energy at high temperature, a fuel cell which is considered to be widely applied as the proton exchange membrane fuel cell (PEMFC) in the future.
 
SOFC does not require expensive platinum as a catalyst with both the anode and cathode materials are oxides. WO3 is a semiconductor-type transition metal oxide, to maintain stability in an acidic environment, also form catalytic effect together with the noble metal, as carrier it can partial substitute carbon to prepared composite catalyst which has been extensively studied. We guess that perhaps WO3 catalysts can be used in SOFC. The work environment of fuel cells has the properties of high voltage, humidity and low pH values, thus requiring an electrode material has good corrosion resistance. Pt / WO3 / C being the most studied of the fuel cell catalyst, the experimental results showed that the addition of WO3 in the catalyst will bring the significant improvement of oxidation catalytic activity and electrochemical oxidation stability; the same time, most of the fuel cells take methanol, ethanol as the energy source and thus there is inevitable to generate amount of CO in the reaction process, while the addition of WO3 in the catalyst of the CO stripping experiment found that Pt / WO3 / C exhibited good CO oxidation, that is, it has good resistance CO poisoning ability.

Tungsten Carbide Business Hit By Oil&Gas Malaise

The full-year profits took a hit from the on-going malaise in the Oil&Gas sector, although management sounded an optimistic note on the potential of its products, including graphene.
The advanced engineering materials group recorded losses before tax of £1.8m, up from £0.9m in 2015.
Revenues declined 10% from £4.98m to £4.4m, with improved sales at its thermal products arm failing to offset a drop in Hard Wear products unit.
Its tungsten carbide business took a hit from the downturn in the oil and gas sector, reporting sales for the year to end March of £3.1mln compared to £4.6mln in 2015, but it said all three of its divisions, hardware, thermal and graphene, had made progress.

Sales at the former, which manufactures microporous copper foam, improved from £0.4m to £1.3m, benefitting from the purchase of its heat sink business in February 2015.
In parallel, Hard Wear product sales were hit by the adverse environment in the oil and gas market, although new opportunities were emerging in defence and aerospace, the company said in a statement.
The unit makes sintered tungsten carbide business for "arduous environment" applications, primarily in Oil&Gas.
Since the end of the reporting period, the company had closed four partnerships to introduce its grapheme products into four key markets: batteries, carbon fibre products and enhanced composites for 3D printing and the aerospace industry.
It had also negotiated its first OEM contract for the use of low profile copper foam heat sinks in consumer devices.

Cash at period end was down from £3.5m one year ago to £1.6m, with £1.26m having been funneled into operating activities and another £276,000 towards the purchase of intangible assets.
Regarding the company's outlook, the board said it remained confident it was on track to benefit from progress made, saying that graphene was moving quickly towards commercial applications, while thermal products had moved into commercial production.
As of 15:56 BST shares in AIM-listed Versarien were 6.38% down to 11.0p.tungsten carbide button

 

WO3 Denitration Catalyst Devotes to Green Energy

With the whole society to improve air quality concerns, China in recent years regarded environmental protection as an important work and expanded, the emerging energy, chemical and other industries are required to must equipped with exhaust gas purification, waste water treatment equipment; also, the old coal enterprise are asked to carry out reforming and installing some equipments to the boiler, thus the ultra-low emissions has become the mainstream environmental topics. 

three forms of SCR denitration catalyst
 
Media recently reported that Power Plant of Tongliao, Inner Mongolia of China, has started a wide load denitrification renovation project on its No.5 Unit from late May this year and it has been completed with the ongoing production and other external insulation finishing work. According to the source, this transformation is due to the No.5 unit has the situations of lacking of steam and temperature under the high-load condition, denitration can not to be put into operation under the low-load. The reconstruction project team increased the flue gas temperature by the mean of increasing flue gas bypass under the premise of ensuring the thermal efficiency not to be reduced compared with that of before the transformation, mode of boiler operation and adjustment method meet the boiler stability and security operational requirements and also no to increase the total flue resistance. And thus achieve the goal of full unit load denitrification, and make contributions to the undertaken of green and clean energy.
 
Denitration catalyst is installed in the SCR denitration catalyst system, which can be divided into three forms of plate, honeycomb and corrugated plate from the appearance. The most commonly used SCR denitration catalyst, no matter what form the ingredients are, they are almost similar in the ingredient, which is taking vanadium pentoxide as main active substance, WO3 as a co-catalyst, titanium dioxide as a carrier. Vanadium pentoxide is very active and will oxidize sulfur dioxide to sulfur trioxide during the production of sulfuric acid. WO3 as the co-catalyst, its presence can reduce the catalytic oxidation of sulfur dioxide at maximum under the basis of catalytic reduction of NOx is to be guaranteed, and thus to improve the denitration catalyst thermal stability and resistant to the As and other toxic substances in the flue gas. In addition, on the presence of WO3, it can be avoid that catalyst carrier occurs changes in the crystalline structure which cause the carrier sintering during the operating process for long-term, to minimize the sintering of the catalyst, thus maintain the specific surface area not to be reduced and affect catalyst activity.
