The Raman spectrum of silicon carbide has been observed by Narayanan , who reported a strong line at 818 cm" 1 (12.2 p). 3. a typical example of this appliion is shown in figure 5. The upper curve is the emission, normal to the surface, from a sand a
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.
