boron carbide

Description: Boron carbide bulletproof armor plate is made by sintereting boron carbide abrasive grain in the high pressure vacuum sintering furnace, from room temperature to a certain temperature, keep this temperature for several hours then naturally cooling to room temperature again, then processing it mechanically to reach a required tolerance. Applications: Boron carbide bulletproof armor plate is suitable for making lightweight bulletproof armor, using to protect aircraft, vehicle, naval vessel and making bullet-proof vest.
