Abrasive material，Sandblasting media
China [CN] Boron Carbide powder B4C is smelted from boric acid and powdered carbon in electric furnace under high temperature. It is one of the hardest man-made materials available in commercial quantities that has a finite melting point low enough to permit its relatively easy fabricationinto shapes. Some of Boron Carbide’s unique properties include: high hardness, chemical inertness, and a high neutron absorbing , cross section.
