Sic ninety seven.8% Black Silicon Carbide for Coated EPT
Black silicon carbide is developed at substantial temperature in an electrical resistance type furnace with quartz sand and petroleum coke as its principal raw supplies. Its hardness is in between fused alumina and artificial diamond.
The mechanical depth of black silicon carbide is greater than that of fused alumina. It is brittle and sharp and has electrical and warmth conductivity in some diploma. Black silicon carbide is suitable for grinding forged iron, non-ferrous steel, leather, rubber, wood, rock, it also be used as high grade refractory content.
Black Silicon Carbide (SiC) is a male made mineral of intense hardness and sharpness. It is the best abrasive for grinding / sXiHu (West Lake) Dis.Hu (West Lake) Dis. supplies of minimal tensile power such as Cast Iron, Brass, Aluminum, Bronze and so forth. Its thermal qualities make it an outstanding medium for use in the manufacture of refractory items and crucibles.
