Boron carbide powder：
Boron Carbide 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 fabrication into shapes. Some of Boron Carbide’s unique properties include: high hardness, chemical inertness, and a high neutron absorbing
