Boron Carbide Powder
Boron carbide powder is a kind of gray black powder in appearance. It is one of the three hardest materials known. Boron carbide powder has the characteristics of low density, high strength, high temperature stability and good chemical stability. It is commonly used in tank armor, bulletproof clothing and many industrial applications.
Boron Carbide Powder Application
Boron carbide powder is widely used in superhard materials, diamond tools, neutron counters, neutron absorbers and reactor control rods, thermal spraying surface coatings and so on. According to different applications, we can provide boron carbide powder suitable for different occasions and fields, the details are as follows:
Boron Carbide Powder for Sintered Ceramics
Boron carbide ceramic powder has the characteristics of high melting point, high hardness and low density. It is a good substitute in the application field of bulletproof materials. The high hardness ceramics made of boron carbide powder can be used in bulletproof vests, bulletproof vests and bulletproof helmets, as well as in the additional top, hatch cover, exhaust plate, turret seat ring, bulletproof glass, pivot frame and other armor components of bulletproof armor, as well as the lower body of tank vehicles. It can also be used to make trunk plate, side plate, vehicle door and driver's seat. In addition, the ceramics made of boron carbide powder can also be used in bulletproof armor, armed helicopters, police and civilian special vehicles and other equipment.

Boron Carbide Powder for Grinding
Boron carbide powder abrasive has good performance in double-sided grinding of sapphire wafer and back thinning polishing of sapphire based LED epitaxial wafer. Due to the high strength and hardness of sapphire crystal, the surface will be scratched when grinding sapphire wafer with artificial diamond, which will affect the light transmittance of the wafer, and the price is expensive. When silicon dioxide is used for grinding, there are problems of insufficient hardness and poor grinding force. Therefore, boron carbide abrasive becomes an ideal material for machining and grinding sapphire crystals.

Boron Carbide Powder for Refractories
Boron carbide powder can be used as antioxidant additive for low carbon magnesia carbon brick and castable. In the iron and steel industry, boron carbide powder is often used in the key parts of high temperature resistance and erosion resistance. At present, the service performance of low-carbon magnesia carbon brick is generally improved by improving the combined carbon structure, optimizing the matrix structure of magnesia carbon brick and adding high-efficiency antioxidants. The graphitized carbon black composite powder composed of industrial grade B4C and some graphitized carbon black can be used as carbon source and antioxidant in low-carbon magnesia carbon brick.
Boron Carbide Powder for Welding Rod
Boron carbide wear-resistant electrode can be used for surface strengthening surfacing of mechanical parts with strong abrasive wear below medium impact. Adding a large amount of boron carbide powder and a small amount of tungsten, vanadium, niobium, rare earth alloy elements and various alloy element additives to the coating improves the welding process performance. The hardness of the surfacing layer can reach HRC65 ~ 70, and the wear resistance is 17.38 times that of quenched 65Mn steel.
