Available size of boron carbide Boron carbide is produced by high-temperature smelting of boric acid and carbon materials in an electric furnace, with a theoretical density of 2.52g /cm3, the melting point is 2450°C, and the microhardness is 4950kgf/mm2. Its hardness is second only to diamond and cubic Boron nitride has the characteristics of high

Application of boron carbide at home and abroad

Development Trend of Boron Carbide Boron carbide is a very hard boride. Because of its high temperature resistance, acid and alkali corrosion resistance, high strength, high chemical stability, light specific gravity and other characteristics, it is widely used in grinding, grinding, drilling, etc. of hard materials, machinery, aerospace, national defense, electronics, Bulletproof armor, chemical additives,

Application of Boron Carbide in Nuclear Industry Boron carbide has a high neutron absorption cross section and a wide energy spectrum for absorbing neutrons, and is often used as a neutron absorbing material for nuclear reactors. Among them, the thermal cross section of the boron-10 isotope is as high as 347×10-24cm2, second only to a

Boron carbide: the main force in the new material industry Foreign countries began to study and use boron carbide as early as the 1960s. my country’s research on boron carbide started late, but it has also formed a considerable scale. At present, the application of boron carbide in my country is mainly concentrated in the
