CVD Silicon Carbide® - Insaco Inc.

Silicon Carbide is industrially produced by sintering, reaction bonding, crystal growth, and chemical vapor deposition (CVD). Silicon carbide offers low density and high stiffness, as well as extreme hardness and wear resistance. The CVD material can be produced with such low electrical resistance (around one ohm cm) that it can be considered a reasonable conductor of electricity. Although
