Silicon carbide is produced commercially by reaction of a mixture of sand (silica) and coke (carbon) in an electric resistance furnace: (1) SiO 2 ( 1 ) + 3 C(s) → SiC(s) + 2CO(g) This self-conducting mixture is heated by direct current to temperatures up to 2700 °C and the product is obtained after several days as an aggregate of iridescent
Silicon carbide materials had also been widely studied for quantitative calculation of residual stress using Raman spectroscopy [88,89,90,91,92]. Figure 14 shows typical Raman spectra of the LO and TO modes at different pressures obtained from a single crystal 6H-silicon carbide . It was obvious that the Raman shift of the LO and TO modes was
