Bismuth tungstate (Bi₂WO₆) is a layered structure with dielectric, luminescent and ionized conductors. Bismuth tungstate has photocatalytic properties under visible light. Bismuth tungstate can photolysis water and photodegradation organic pollutants under visible light. Therefore, Bismuth tungstate has good application prospects in many related fields.

Tungsten has high melting point, strong electron emission ability, low electron escape work, high elastic modulus and low vapor pressure, so it is very suitable for non-molten argon arc welding electrode materials.

TiC cermets consisting of hard phase and bonding phase are the best choice of indexable tool materials for modern high-efficiency and high-speed cutting because of their higher hardness and wear resistance, sufficient strength and toughness, high heat resistance and good chemical stability. However, its fatal weakness is brittleness and toughness is insufficient, and the matching wetting problem between hard phase and bonding phase has not yet been solved.

Because of its large specific surface area and remarkable surface effect, nano-tungsten trioxide has been widely used in various gas-sensing materials, and has become one of the indispensable materials for many high-quality gas-sensing materials. At present, the preparation methods of nano tungsten trioxide are mainly sol gel method, co precipitation method, microemulsion method, physical deposition method and so on. Microemulsion method has been widely applied in recent years because of its simple process.
