Descriptions
Silicon carbide (SiC), also known as carborundum, is a compoundof siliconand carbonwith chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sinteringto form very hard ceramicswhich are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic platesin bulletproof vests. Electronic applications of silicon carbide as light emitting diodes(LEDs) and detectorsin early radios were first demonstrated around 1907, and today SiC is widely used in high-temperature/high-voltage semiconductor electronics. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from SiO2contained in plant material.
Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C.
HIJO Abrasives offers a whole range of macro and micro grits in green silicon carbide, quality and various particle size distributions based on FEPA, and JIS standards.
