Boron Carbide Invention

Alumina Ceramics ScienceDirect

Alumina was the original ceramic in lightweight body armor, and remains one of the two main ceramics used in this role today, with SiC (silicon carbide) the other main ceramic. B 4 C (boron carbide) is also occasionally used in spite of its problems of high cost and premature failure due to the B 4 C shock-loading problem.
