Ceramic Armor - DIAMOND AGE

May 15, 2018· Silicon Carbide (SiC) is lighter in weight than alumina, and is slightly superior in terms of performance. The cost of silicon carbide armor pieces is, however, more than five times higher than equivalent alumina pieces — this is on account of the fact that silicon carbide is more difficult to work with, as far higher temperatures and tighter

Synthetic Moissanite: A New Diamond Substitute

those of diamond (table 1). Silicon Carbide. Since it was first manufactured a century ago, silicon carbide (SiC) has played an important industrial role as an abrasive. The growth of single crystals of silicon carbide has been studied for many years for two possible end uses: as a semiconductor material, and as a diamond substi-tute in jewelry.
