Tungstate, as a new photocatalyst, has good optical properties and few electron recombination centers. Among them, bismuth tungstate Bi₀WO₆ photocatalyst is the most popular. Bismuth tungstate photocatalyst has good ultraviolet and visible photocatalytic properties. It can utilize both ultraviolet and visible light in sunlight. It has a good application prospect in environmental purification.

Selective Catalytic Reduction (SCR) flue gas denitrification technology has the advantages of high denitrification efficiency, good selectivity, maturity and reliability. It is widely used in thermal power plants and is the mainstream of denitrification in coal-fired units. The main active components of catalysts used in SCR denitrification are titanium dioxide, V₂O^-, WO₃ and MoO₃, which account for more than 90% of the catalyst composition.

Cobalt tungsten carbide powder has high hardness and excellent wear resistance, and is widely used as cutting tools, wear-resistant tools, impact-resistant tools and metal casting materials. Moreover, when WC powder particles are finer, it has higher hardness and wear resistance.

Tungsten disulfide is a typical sandwich layered structure. Because of its relatively weak van der Waals force between layers, it can also be peeled into single or few layers of nanosheets. Tungsten disulfide is considered as another important two-dimensional nanosheet material besides graphene, which has unique physical, chemical and electrical properties.
