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

The properties of boron carbide Hard black shiny crystals. The hardness is lower than that of industrial diamond, but higher than that of silicon carbide. Less brittle than most pottery. Has a large thermal energy neutron capture cross section. Strong chemical resistance. Not attacked by hot hydrogen fluoride and nitric acid. Soluble in molten alkali,

Application of Boron Carbide in Refractory Materials Boron carbide is mainly used for anti-oxidation in carbon-containing refractory materials, which can densify the product and prevent the oxidation of carbon in carbon-containing refractory materials. At the same time, at 1000℃～1250℃, Al2O3 reacts with B2O3 to generate 9Al2O3· The columnar crystals of 2B2O3 are distributed in the
