carbon boron carbide used in refractory material from anti-oxidation, so that products can be compact, to prevent carbon-carbon refractories in the oxide, while in 1000 ℃ ~ 1250 ℃ time, Al2O3 and B2O3 react To generate 9Al2O3 • 2B2O3 of columnar crystals in the matrix of refractory material and space, thus reducing the porosity, raise the temperature strength, and generated 9Al2O3 • 2B2O3 crystal, expansion, healing volume contraction to reduce the crack.
Boron carbide in more than 1300 ° C, it almost harder boron nitride and diamond. Flexural strength of boron carbide for 50000-70000 psi, to Naiyaqiangduo 414000 psi. Boron carbide is very low thermal conductivity (29-67 W / mK), resistivity in the range of 0.1 - 10 ohm-cm. Based on the above excellent physical properties, the use of a wide range of boron carbide.
