Tungsten titanium alloy target with low resistance coefficient, good thermal stability and oxidation resistance properties, diffusion barrier layer has been successfully applied to Al, Cu and Ag wiring, and has been widely studied and applied in semiconductor and solar energy industries in terms of sputtering.

In recent years, with the continuous development of science and technology, spherical tungsten powder is widely used in thermal spraying, porous materials and powder metallurgy industry, and its demand is also increasing. In the field of thermal spraying, the spherical tungsten powder is not only well fluidity, but also the coating is more uniform and compact, so the product has better wear resistance.

Tungsten tailings are the solid wastes produced after the classification of tungsten ore. At present, the comprehensive utilization mainly includes the recycle of useful metals and non-metallic ores, but the amount of metal recycle components is small and a large amount of tailings remains. It is used in the production of glass ceramics, ceramics, fire free bricks and hollow bricks, with limited use, high process cost and limited application benefit.

Tungsten copper alloy is made up of copper powder and tungsten powder at a certain proportion, which is made by powder metallurgy. The material combines the advantages of tungsten and copper, and is widely used in military materials, electronic packaging materials, electrical sink materials, electrode materials and other fields. With the prolongation of the use time and the decline of the function of the tungsten copper alloy, the tungsten copper alloy has been dropped out of the application field and became waste.

Zinc tungstate is a kind of tungstate. Its molecular formula is ZnWO₄. As a photocatalyst, zinc tungstate has a white appearance and its particle size is mostly nanometer grade.

Bismuth tungstate is a kind of tungstate with white powder in appearance and chemical formula Bi2WO6. It is a kind of visible light semiconductor photocatalyst with high attention.

Wolframite and scheelite ore in China is mainly a kind of tungsten ore mining in recent years, the strata are mainly quartz veinlet belt type and layered dip type tungsten deposit.

With the continuous exploitation of tungsten resources, the reserves of wolframite, especially high-grade wolframite, are getting less and less. The scheelite and the medium ore with high impurity content become the main sources of tungsten smelting raw materials.
