Black silicon carbide is black, and its microscopic shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.2, the microhardness is 3000-3300 kg/mm2, the hardness is 2670-2815 kg/mm, and the microhardness is 3300 kg/mm3. The density is generally considered to be 3.20 g/mm3, and the natural bulk density of its silicon carbide abrasive is between 1.2-1.6 g/mm3, and the specific gravity is 3.20-3.25. The particle size sand number is 12/14/16/19/20/22/24/26/30/36/46/60/80/90/100/120/150/180/240/280. It is mainly used for grinding and polishing of hard alloys, titanium alloys, stainless steel, copper, aluminum, zinc, ceramics, stone, agate, jade, high-end jewelry, electronic components and other materials. It can also be used to manufacture molds and advanced refractory materials. It can also be used in other industries.
Black silicon carbide has a relatively long service life, is relatively hard, and its price is more in line with the current public's choice. It has a relatively complete range of specifications, is wear-resistant, and has great effects. It is also because of these characteristics that black silicon carbide is now used in many industries and is very popular with customers.
