Boron Carbide is the hardest man-made material next to synthetic diamonds. It is recommended for use on very hard materials such as sapphire, ruby, tungsten carbide and ceramics. In some cases, it can be recirculated as it does not break down as rapidly as other abrasives.
Typical applications are lapping, grinding and bulletproof armor.
