Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More
The influence of the removal depth of a silicon modifiion layer on grating structures and mirrors is studied. The removal depth 6–14 μm is the optimization result for Si-modified reaction-sintered silicon carbide (RS-SiC) used as mirror substrates, but the removal depth 9–12 μm is the optimization result for Si-modified RS-SiC used as grating
