Cas no 12069-32-8 (Boron carbide)
Boron carbide (B?C) is a synthetic ceramic material renowned for its exceptional hardness (9.3 Mohs), ranking third behind diamond and cubic boron nitride. It exhibits high thermal stability (melting point ~2,350°C) and outstanding resistance to wear, abrasion, and chemical corrosion. With a low density (2.52 g/cm3), it is ideal for lightweight armor applications. Its neutron absorption properties make it valuable in nuclear shielding. Boron carbide also demonstrates high mechanical strength and thermal conductivity, suitable for abrasive and cutting tools, as well as high-temperature industrial components. The material’s combination of durability, thermal properties, and lightweight nature makes it a preferred choice for demanding engineering and defense applications.
