Boron Carbide

Boron Carbide (B4C) Description


Boron carbide is the third hardest substance known, after diamond and cubic boron nitride, earning it the nickname “black diamond”. It has a Mohs hardness of about 9.49. Meanwhile, it has good chemical inertness and high neutron absorption cross section.


Its hardness and extremely low density make it used as a reinforcing agent for aluminum in military armor and high-performance bicycles, and its wear resistance makes it used in blast nozzles and pump seals. The neutron absorber boron carbide is used in powder or solidified form to control the fission rate in nuclear reactors.
