Boron carbide which has the chemical formula of B 4 C is one of the hardest materials among the ceramics materials after diamond and boron nitride. In addition to its hardness, it has high thermal stability, low density, chemical inertness and neutron capture property. At temperature above 1200 o C, its hardness exceeds that of the diamond. Thus, it is a crucial material for high technology applications such as abrasive for polishing and grinding media, ceramic amour applications for personal purpose and equipment, blasting nozzles, ceramic bearings, semiconductor applications for dielectric barriers, medical and nuclear applications. B4C (Boron Carbide) Nanoparticles (99.5+%, 40-60nm, Hexagonal) show an outstanding hardness among the ceramic materials. Therefore, boron carbide nanoparticles are a suitable material for many high performance applications. Boron carbide nanoparticles can be used as polishing, lapping and grinding material for hard mater...
