Abrasives high quality boron carbide for ballistic armor plates. boron carbide is produced by high temperature smelting boric aid and carbon materails in electric furnaces. When high protection levels in lightweight designs are required, 3m™ lightweight body armor plates offer a versatile solution that can be designed to meet specific customer requirements. these plates are manufactured by combining hot pressed boron carbide or silicon carbide ceramic with optimized composite structures to produce a rugged, multi-hit armor in a number 3m technical ceramics offers hot pressed boron carbide plates in different designs and sizes. for example a double curved plate in sizes s through xl, a multi curved plate and a single curved side plate. the thickness of the plates can be adjusted to meet the specic threat requirements. This unique combination led to the rapid adoption of boron carbide for high-end armor systems — allowing them to be lighter and more effective. applications for boron carbide plates have included aircraft armor and elite body armor.
