BGrinding materials B4C Boron Carbide F280 Price

 

     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
