Tungsten carbide (WC) has been widely used in catalysis because of its platinum-like catalytic activity, high hardness, high thermal stability and good wear resistance. As a catalyst, WC has not only good catalytic activity for hydrogenation and dehydrogenation, but also selective catalysis for some reactions.

Foamed metal tungsten is a kind of material with double properties of function and structure. It has certain strength, high temperature resistance and corrosion resistance, and has low density, high porosity and large surface area. It is widely used in modern defense and military, atomic energy, aeronautical and aerospace, electronic information and other fields.

Ammonium paratungstate is an important intermediate product in tungsten hydrometallurgical process. The production process of tungsten concentrate decomposition-ammonium paratungstate mainly includes ore decomposition, transformation to obtain crude ammonium tungstate solution, impurity removal from crude ammonium tungstate solution, crystallization to obtain ammonium paratungstate and crystallization mother liquor, recycling of crystallization mother liquor, etc.

Molybdenum and tungsten resources are China's dominant resource minerals. China's reserves of molybdenum and tungsten resources, mining and processing volume, and trade volume occupy an important position in the world, while tungsten is in the first place. Tungsten mainly exists in the form of black tungsten and scheelite. The scheelite often contains a certain amount of molybdenum, which is usually in the form of molybdenum sulfide, which can be separated by conventional flotation methods. The tungsten resource containing molybdenum oxide is difficult to process. It is rarely used.
