The core of hydrogen evolution materials is catalysts. The traditional platinum catalysts have strong catalytic performance. They have always been the dominant materials in this field. The shortcoming is that platinum metals are too expensive and can produce toxic by-products. Therefore, it is of great significance to find hydrogen evolution materials with low overpotential, low cost, high earth content and large-scale synthesis.

Tungsten carbide cemented carbide has a series of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at 500 ℃ and still have high hardness at 1000 ℃.

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.

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.

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.

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.

Tungsten deposits are the traditional superior mineral resources in China. There are many kinds of tungsten deposits in China. The causes of mineralization are complex and the forms of mineralization are diverse. With the large-scale development and utilization of tungsten resources and the continuous improvement of beneficiation and metallurgical technology, high-quality primary tungsten resources are consumed in large quantities, the boundary grade of tungsten mining is decreasing day by day, and many associated tungsten resources are reused by people.

With the application of cemented carbides becoming more and more extensive, and the performance requirements tend to be a combination of high strength, high hardness and high temperature resistance. Some enterprises have adopted a new preparation process to prepare tungsten carbide ceramic cemented carbide. The process is as follows:
