Boron Carbide ( chemical formula approximately B4C ) is a ceramic material with high hardness and low density. Boron carbide is stiffer and harder than silicon carbide or tungsten carbide. Due to the high hardness and high wear resistance, boron carbide ceramic plates are widely used in the wear-resistance industry. The life-span of those products,

Boron Carbide (B4C) This material is a hard Boron–Carbon Ceramic, with hardness ranking only behind the diamond. Properties of Boron Carbide High hardness Low thermal conductivity High elastic modulus High melting point High strength High wear resistance Good nuclear properties Low density What’s the future for Boron Carbide? Given their unique properties and proven versatility,

Two kinds of boron carbide powders, S-1 and S-2, were prepared by the reaction of boric oxide with carbon black in magnesium (2B2O3+6Mg+C=B4C+6MgO). Powder S-1 was prepared by heat-treating for 10min at 1500°C immediately after the reaction was completed, while S-2 was prepared by heat-treating at 1650°C. After purifying the powders, the chemical composition of
