Laboratory extinction spectra of grains of α silicon carbide are available which compare well with the astronomical observations. Unfortunately, these measurements are not sufficient to fully interpret the 11.5 μm feature profiles since radiative transer models require the knowledge of the complex refractive index of the circumstellar material over the whole electromagnetic spectrum. In
For long-wave radiation, the refractive index does not practically change, although in a region close to its own absorption the refractive index can change its value. According to the data of [ 25 ], in the wavelength region up to 440 nm (band-band transitions and above), the refractive index of silicon carbide varies nonmonotonically in the range of 2.4–3.4.
TGA and DSC curves of silica wires prepared without any surfactant are shown in Figure 5a. The results showed a drastic weight loss up to about 87.5% in the range 20−220 C accompanied by an
Abstract. The refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal

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.
