Lightweighted telescope mirrors: Outstanding properties of Silicon Carbide
silicon carbide is deposited on a heated substrate at temperatures higher than 1300 C. As a result, a beta-SiC is obtained. This polytype of SiC is almost fully dense and has very fine columnar grains. Beta-SiC is then deposited on a graphite or SiC bulk
Silicon Carbide SiC Material Properties
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
