Tungsten market off season ended last week, the flowing trend is unobvious, market is in an intensive situation. Demand still doesn’t increase. Tungsten market volume of business keeps decrease, most enterprises hold wait and see attitude for tungsten market.

Tungsten market not only needs demand but also stability of market. Last week, some enterprises sell the price below market level which is challenging the confidence of market. However, volume of business is still small.

Last week, tungsten products price changes originates from ammonium paratungstate, the mainstream enterprises maintain stable quotation. Some large metallurgy factories say that due to the cost of raw material, ammonium paratungstate price won’t decrease in the next few weeks. APT quotation stays 105~107 thousand RMB/ton. Some other enterprises show that they have advantages both in raw material cost and manufacturing cost. In order to sell the product intiative, quotation maintains at 103~105 RMB/ton, but the selling amount is negative.

Today the indicative price by Ganzhou Tungsten Industry Association, China Minmetal and Jiangxi Rare Earth and Rare Metals Tungsten Group Corporation will come out. It will indicate market price and keep the mainstream stay positive. The indicative price is mainly based on support market confidence, it will be a bit higher than spot market.

The future market trend will greatly depend on this week. It will either turn splendid or fade away. Break weak balance of market is easy, but there is no one who will intervene market balance. Although supply and demand are the most important factors, tungsten price is already below the cost level which is unchangeable. We predict that in short times market will turns weaker and stay stable in the whole as a whole. Dynamic of large enterprises is a key to market, once the stimulus appears, to promote and develop the market is not difficult.

In 1991, the movie "Terminator 2" appears in a powerful robot T-1000, the use of liquid metal to create a robot no matter how much harm can be met with an instant automatic recovery, and even can change the body shape and facial appearance. This deformation robot scientist has always been one of the goals, and now, a study by Chinese scientists in the field of liquid metal eligible for a breakthrough in the long road of research and a small step forward. New research allow liquid metal machine can "run" can "jump".

Liu Jing team research group reported an unusual unique self-oscillation effect of liquid metal solid-liquid combination machine: when the tungsten copper wire touches treated aluminum-containing liquid metal, tungsten copper wire are quickly swallowed by the liquid metal, and then made a long shuttle back and forth movement of the liquid metal in the body, like playing the violin string music in general.

Tungsten copper wire with heat ablation resistance, high strength, electrical conductivity and other characteristics.

The authors found that a class of interesting liquid metal jump behavior: There is added to the discharge of solid metal particles (tungsten, nickel, copper, iron, etc.) solution system of metal droplets, the original stationary metal droplets began to beat up and leaving a string of cake in the bottom of the container "footprint."

Research revealed that the surface of the metal particles and liquid metal point contact occurs when the electric field strength at the interface significantly enhanced, as well as in the solution within the electrolysis hydrogen production, hydrogen bubbles are formed in the substrate continues to grow adsorption "gas spring", which droplets jump provide thrust. One of the factors leading to the electric field polarization between the liquid metal from the metal particles with solid potential difference that is galvanic effect; the other reason is that the solid - liquid material microstructure differences between the interface will lead to charge accumulation, sparking tip discharge effect.

Research team by a plating method in the liquid metal surface mount ferromagnetic nickel layer, thereby realizing flexible control of the machine in an external magnetic or electric field and verify its potential value in terms of drug delivery. Beyond the random motion of the liquid metal type machine it is that the magnetic solid-liquid combination can be achieved from the machine stop motion, steering and acceleration of complex behavior.

Furthermore, the team also developed a kind of flexible deformable "wheels" driven miniature vehicle, its body is made of plastic and metal droplets through a combination of 3D printing. In the electric field, the liquid metal "wheel" can rotate deformed, and then drive the vehicle travels, and even accelerate the realization of more complex motion.

Liu Jing study team found that in the electrolyte, a liquid gallium based alloy, after "swallowing" Aluminum as food or fuel, can actually deformed shape long high-speed motion machine to achieve without external power autonomy movement.

In recent years, Liu Jing team has been working to promote joint industry liquid metal industrial applications. She said: We have the opportunity to study in the liquid metal in the world to go ahead, but can not lag behind in terms of industry, we need to seize the historic opportunity to help build our country into a world-class liquid metal valley.

It is reported from the overseas that US government scientists are creating a "jar stars" replicate the way the sun and other stars to generate energy through nuclear fusion on earth. If successful, the human beings will get inexhaustible energy, and no longer need to rely on fossil fuels to produce the electricity. That would be pretty wonderful.

With the continuous efforts of the international community, the physical feasibility of nuclear fusion reactor has been confirmed, including Tokamak type magnetic confinement controlled nuclear fusion research, the progress in this field has been fastest among the most mature technology.

Princeton Plasma Laboratory, US Department of Energy (abbreviated PPPL) physicists recently in the journal Nuclear Fusion published a paper which showed their research of new generation of nuclear fusion equipment plans. PPPL laboratory and England Kalam already have a spherical Tokamak. All these will provide ideas to help scientists design a new type of fusion device, as so to build further by a commercial fusion power plant generating electricity.

During researches, the selection of material has always been a key factor to whether the fusion energy could be developed or not. In fusion materials, it is a class of very important materials is plasma material, also known as coating materials. Tungsten alloy has been proved in research and development owing superior physical and chemical properties in a high-energy level, such as high melting point, high density, high density, low vapor pressure, good thermal conductivity and high strength, also stability enough not form a hydride with hydrogen. Therefore, tungsten alloy becomes a very rare coating material applied on the high-temperature flux components.
