Boron Carbide

Also nicknamed "black diamond", boron carbide ranks among the three hardest known materials, with hardness second only to diamond and cubic boron nitride (CBN). It features an ultra-low density of 2.52 g/cm³, a high melting point of 2450 °C, and outstanding chemical stability, remaining inert to both strong acids and strong alkalis.

The core advantage of boron carbide lies in its exceptional neutron absorption capacity. Boron elements possess a large neutron capture cross-section, which enables efficient thermal neutron absorption without generating long-lived radionuclides. This property makes boron carbide an essential material for nuclear reactor control rods, radiation shielding and spent fuel storage applications.

Meanwhile, benefiting from its lightweight and high-strength characteristics, boron carbide is widely adopted in protection fields such as ballistic armor and individual armor inserts. For industrial applications, it serves as a superhard abrasive for grinding and polishing cemented carbides and gemstones, as well as for manufacturing precision components including high-wear nozzles and sealing rings.
