With the rapid development of industry, more and more attention has been paid to the treatment of water pollution. Bi₂WO₆ tungstate is a narrow bandgap semiconductor (about 2.7eV), which can absorb part of visible light. Bi₂WO₆ is a widely used photocatalytic material for visible light response. It is widely used for photocatalytic degradation of organic dyes, drugs, heavy metals and other pollutants.

Tungsten is an important strategic material, which is widely used in tungsten carbide tools, filaments, tool steel additives, rockets, space vehicles, nuclear reactors and other fields.

Because of its excellent electrical, optical and thermal properties, two-dimensional materials have aroused the enthusiasm of non-mathematicians and attracted extensive attention in the field of materials science. Two-dimensional tungsten disulfide is a new type of graphene-like two-dimensional material, which has great potential for applications in electrical devices, energy, biology and composite materials.

Lead tungstate is an important inorganic scintillator material. Because of its excellent scintillation properties such as short attenuation time, high irradiation hardness, high density and low cost, it has been widely used in many fields such as light emitting, optical fiber, photocatalysis, microwave, scintillator, detector and so on.
