Product Description

Boron carbide powder

 

Boron carbide powder is hard black with glossy crystals. Hardness is lower than industrial diamond, but higher than silicon carbide. It is less vulnerable than most pottery. It has a large thermal neutron capture cross section. Strong resistance to chemistry. The erosion of h ydrogen fluoride and nitric aci d. Soluble in molten base, insoluble in water and acid.
