Properties of Silicon Carbide Ceramic Materials
Properties of silicon carbide ceramic materialsChemical properties of silicon carbide ceramic materialsWhen the temperature in the oxygen reaction reaches 1300 ° C, a protective layer of silica is formed on the surface of the silicon carbide crystal. With the thickening of the protective layer, the internal silicon carbide is resistant to continue to combine, so that silicon carbide has good chemical resistance. In terms of acid resistance, alkali resistance and compound resistance, silicon carbide has strong acid resistance and poor alkali resistance due to the role of silicon dioxide protective film.Physical properties of silicon carbide ceramic materialsThe density of various sic crystals is similar, usually 3.20 g/mm³. Silicon carbide has a hardness of 9.5 Mohs and a Knox hardness of 2...
