Tungsten is a very valuable resource of rare metal resources, one of the tungsten industry as an important modern industrial materials industry, is significant.

Tungsten is a hardness, melting point, high strength and good metal, machinery, steel, defense industry and other fields are widely used. Its main application is the carbide industry, it is often said of tungsten steel. Carbide is called modern industry teeth. Tungsten resources as an important strategic resource, and more emphasis on the protection of world powers tungsten resources. Our country has also set up since the 1990s Industry Association, introduced a number of laws and regulations, strict supervision, tungsten resources.

Global reserves of tungsten resources are scarce, centralized distribution. China has proven reserves of 65.5% of the world, it has obvious advantages. Since 2001, China began to implement tungsten resource extraction quotas and export quotas, effectively inhibited the global tungsten supply. Coupled with decreasing the amount of foreign supply, limited availability of recycling waste tungsten, tungsten supply growth is slow.

Tungsten carbide is mainly used in steel and alloys, chemical industry, which accounted for an amount of carbide about 50%. Production of carbide cutting tools only about 25% of total production, 65% of consumption in developed countries accounts for carbide cutting tool consumption, China's carbide broad space for development in the future. "Twelfth Five-Year Plan" clearly encourage new materials containing tungsten or tungsten as a new impetus to the demand.

Tungsten resources are rare Chinese have absolute advantage, as the country gradually strengthen the industry consolidation, supply growth will gradually slow down, while demand in areas such as carbide rapid growth in the long term, the future supply of tungsten would be more many in the tight state. Our industry relies on tungsten carbide absolute advantage in the inevitable development resources more quickly.

Producing fine tungsten powder by hydrogen reduction of tungsten hexachloride, the producing process which are as follows:
1. Firstly, putting tungsten at middle of the inner tube, each charging amount of 1-1.5kg.
2. After beginning of the experiment, through hydrogen in both inside and outside  tube in the case of heating, the temperature of the chloride reaction section of tube is heated to 800 ℃, the reduction reaction of tube heating to 1000 ℃. The temperature was raised to the desired temperature, heat preservation for 1 hour. So it can remove the water of reactor surface and raw material’s oxide films by through hydrogen.
3. Continue through the hydrogen of outer tube, but the inner tube was stopped through hydrogen, argon instead be used to remove the inner tube of hydrogen.
4. After the inner tube of hydrogen divisible, with argon gas and chlorine gas introduced into the tube, so that the reaction of chlorine and tungsten to produce gaseous tungsten hexachloride and tungsten pentachloride mixture.
5. With the reaction proceeds, tungsten chlori from the inner pipe into the outer reaction section tube, and contact with outer tube hydrogen to form fine tungsten powder.

Bearish sentiment dense tungsten businesses, operating actively weak, tungsten spot market volume was light this week, there is still a low risk of tungsten-based products was down, the domestic scrap tungsten blade or fell 110 yuan / kg in the vicinity.

Macro, agency says about 7% GDP growth in the second quarter, there is room for adjustment of monetary policy; the policy of stimulating investment growth is expected to stabilize in the second half economic rebound; eight of the Steering Group to supervise operations throughout the organization functional integration.

Tungsten market: tungsten market continues deserted run, end demand downturn, tungsten ore buyer continued to suppress the inquiry, inquire as low as 50 degrees scheelite 65,000, most of tungsten ore into a loss, the development of the tungsten industry faced relatively great difficulty. But hold stocks low sellers, buyers and sellers stalemate, the spot market turnover less material to late ore prices or to low consolidation.
