Web17. sep 2015 · As the refractive indices of SiC are larger than those of SiO 2, the refractive indices of transition layer, i.e., the SiC-SiO 2 mixed layer SiC x O y should be larger than those of SiO 2. As another candidate to explain these phenomena, the roughness of SiC/oxide interfaces can be considered. WebSilicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength gives this material exceptional thermal shock resistant qualities.
WebThe 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.
