Metal tungstates are a kind of important inorganic materials. They have good application prospects in optical fibers, scintillation materials, photoluminescent materials, humidity sensors, magnetic devices, microwave applications, catalysts and corrosion inhibitors. Among them, zinc tungstate nanomaterials are good materials for photoluminescence, photocatalysis and gas sensing. However, pure zinc tungstate nanomaterials are less sensitive to hydrogen.

At present, hydrofining catalysts are usually prepared by introducing active metal components from solution or suspension into the carrier through impregnation, and then by drying and calcination. Among them, nickel cobalt molybdenum tungsten sulfide is a highly active hydrodesulfurization catalyst.

Tungsten carbide spraying powder is the basis of preparing tungsten carbide wear-resistant coatings by thermal spraying. To prepare tungsten carbide wear-resistant coatings with self-lubricating properties, self-lubricating additives must be added to tungsten carbide spraying powder. At present, self-lubricating additives mainly include soft metals (Au, Ag, etc.), fluoride (LiF₂, CaF₂, etc.) and so on. Disulfides (MoS₂, WS₂, etc.) and metal oxides (Zr₂O₃, Cr₂O₃, etc.) have been extensively studied as lubricating phases for coatings. 

In many scheelite deposits in China, scheelite is not only associated with scheelite, but also with wolframite. For example, Xingluokeng, Fujian Province, is a super-large wolframite-scheelite deposit, with tungsten reserves of about 300,000 tons, and scheelite and wolframite reserves accounting for half of each.
