Structure and bonding in boron carbide: The invincibility of
Boron carbide, usually described as B 4 C, has the mysterious ability to accommodate a large variation in carbon composition (to as much as B 10 C) without undergoing a basic structural change. We systematically explore how the bonding varies with carbon concentration in this structure and the origin of the fundamental electron deficiency of ...

Boron Carbide Blast Nozzles – When To Use One
Boron Carbide nozzles are the hardest of the three, followed by Silicon Carbide, and then by Tungsten Carbide. Hardness is necessary to order to withstand the wear and tear that the blast nozzle liner will be exposed to by the abrasive used. However, the greater the hardness, the more brittle the material. This is why Boron Carbide nozzles need ...
