silicon carbide, exceedingly hard, synthetically produced crystallinecompoundofsiliconandcarbon. Itschemical formulais SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory ...
The process can be used when surface-modifying silicon surfaces, glass surfaces and metal surfaces and, for the silanization, makes use of a chemical compound of the formula <IMAGE> where R1 and R2 each denotes an alkoxy group or halide group, where R3 denotes H or an alkoxy group, where...
