Depleted uranium composites are the most excellent penetrating core materials due to their excellent self-sharpness. In the early 1990s, based on the international public opinion and environmental pressure caused by the toxicity of depleted uranium materials, the United States began to develop an alternative uranium armor piercing core. material. On the basis of the tungsten-nickel-iron heavy alloy, the researchers designed a tungsten-based heavy alloy armor-piercing projectile through the change of the microstructure of the alloy, but there is still a big gap between the self-sharpening effect of the depleted uranium alloy.

In the textile industry, azo dyes are an important raw material and a large class of organic substances that cause increasing environmental risks. These azo dyes are potentially toxic and difficult to biochemically handle. Therefore, it is of great environmental significance to take active and effective measures to treat and control azo dyes.

Tungsten wire owns high resistivity and melting point, good strength, and low vapor pressure, which is the best material for making incandescent filaments in all pure metals. However, how is the thin tungsten wire made? As the tungsten is hard, brittle, and difficult to proccess.

As a high-tech industry in the 21st century, the rapid development of semiconductor industry has far exceeded the traditional iron and steel industry and automobile industry. Silicon material is the cornerstone of semiconductor industry, but with the increasing integration, the shrinkage of size will mainly lead to leakage and static power density of devices. Recently, transition metal chalcogenides, especially tungsten disulfide and molybdenum disulfide, have attracted much attention in the scientific community due to their excellent electrical, optical and mechanical properties, as well as graphene, as a potential post-silica material.

Electrochromic means that the optical properties of materials change reversibly under the action of an applied electric field. The color and optical transmittance of electrochromic materials can be changed at low voltage, and the fading state of electrochromic materials can be maintained under open circuit condition. With this characteristic, electrochromic devices are widely used in energy saving, optical regulation and other fields. Wisdom window is one of its most representative applications.

Tungsten-based high density alloys are widely used in aviation, aerospace, military and nuclear industries because of their high density, strength, hardness and ductility. It is widely used in aerospace industry as balancing counterweight, shock absorber, kinetic energy armor piercing projectile and armor piercing material, and plasma-oriented first wall material in nuclear industry.

Mining industry, as the pillar of our national economy, consumes a lot of water resources every year. At the same time, flotation treatment also produces a large number of flotation wastewater. Among them, sulfide flotation produces a large number of wastewater containing xanthate, xanthate is the most effective and widely used collector in sulfide flotation. Most xanthate will enter the foam product with the end of flotation. If residual xanthate is discharged directly without treatment, it will cause great harm to the environment.

Cobalt tungsten carbide series is widely used as one of the most important wear-resistant coating materials with excellent properties at medium and low temperatures. Many developed countries such as the United States, Russia and the United Kingdom have carried out a lot of research work in this direction. They have formed many kinds of materials preparation methods, such as electrofusion crushing, sintering crushing, polymerization, coating and so on. Cobalt tungsten carbide coatings with different grades and different applications have been designed and prepared.

Tungsten copper based alloy is a pseudo-alloy composed of high melting point, high hardness tungsten and high conductivity and thermal conductivity copper. It has good arc erosion resistance, fusion resistance, high strength and high hardness. Contact materials for various types of ultra-high voltage, high voltage, medium voltage circuit breakers, transformer changeover switches, vacuum contactors, load switches.

With the development of science and technology, the research trend of self-lubricating technology is that solid lubricating materials without environmental pollution, long wear-resistant life, low friction and self-repairing are more and more widely used in high-tech fields such as electronics, biology, communications, aerospace and aviation. Future research mainly focuses on the research of new solid self-lubricating materials, new self-lubricating methods, new material structure design and other aspects.
