Description

Boron carbide is a gray-black powder with a rhombohedral structure. Its most important performance lies in its extraordinary hardness (Mohs hardness 9.36, microhardness 49Gpa), second only to diamond and cubic boron nitride, especially near At constant high temperature strength, making it a high temperature wear-resistant material;

The density of boron carbide is very small (the theoretical density is 2.52g/cm3), which is the lightest among ceramic materials, so it can be used in the aerospace field;

The neutron absorption ability of boron carbide is very strong. Compared with pure elements B and Cd, it has low cost, good corrosion resistance and good thermal stability, so it is widely used in the nuclear industry;

Boron carbide has excellent chemical properties. It does not react with acids, alkalis and most inorganic compounds at room temperature. It only has slow corrosion in hydrofluoric acid-sulfuric acid and hydrofluoric acid-nitric acid mixtures. It is one of the most chemically stable compounds. one;

Boron carbide also has the advantages of high melting point, high elastic modulus, low expansion coefficient and good oxygen absorption capacity

Application:

Boron Carbide - Fine and Advanced Grinding Material
Due to its high grinding efficiency, boron carbide is mainly used as a grinding medium in the grinding process of materials, such as: grinding, grinding, drilling and polishing of hard materials such as gemstones, ceramics, tools, bearings, and cemented carbide.
Boron carbide - the choice of industrial ceramic materials
Products pressed from boron carbide powder: sandblasting nozzles, sealing rings, nozzles, bearings, plungers for mud pumps, pestles and rocket launchers, ceramic coatings for warships, helicopters, etc. As a new type of material, It has the characteristics of high melting point, high hardness, high elastic modulus, strong wear resistance and good self-lubrication, and is widely used in sandblasting machinery, electronics, information, aerospace, automobile and other industries.
