CAS 12069-32-8 Boron Carbide Powder B4C with hardest of the conventional abrasives


Brief Description of Boron Carbide Powder B4C


Boron carbide (chemical formula approximately B4C) is an extremely hard boron-carbon ceramic  and covalent  material 


With a Vickers Hardness of >30 GPa, it is one of the hardest known materials, behind cubic boron nitride  and diamond.


Its Mohs hardness is 9.36, melting point 2350℃, density 2.51g/cm3.


Boron carbide steel, jewel, hard ceramic and other hard materials, and to manufacture wear-resisting parts, metal cutting tools, nozzles and neutron-absorbing rods
