Silicon Carbide l\u00e0 g\u00ec?<\/h2>\n\n\n\n

Silic cacbua<\/a> (SiC) is an inorganic compound. It is a semiconductor and occurs naturally in the extremely rare mineral moissanite. Silicon carbide is commonly available in two varieties: black silicon carbide and green silicon carbide, both of which are \u03b1-SiC. The particle size of silicon carbide ground by jet milling typically ranges from 3 to 100 microns (d97). It’s depending on the type of equipment, process parameters, and raw material characteristics. Black silicon carbide contains approximately 95% SiC and has higher toughness than green silicon carbide. It is mainly used for processing materials with low tensile strength. Glass, ceramics, stone, refractories, cast iron, and non-ferrous metals can use it during production.<\/p>\n\n\n\n
