DescriptionsSilicon carbide is a man-made material manufactured through heating silica sand and carbon to high temperatures in the Acheson furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high temperatures. Silicon carbide's varied properties make it an effective material in many different applications.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.
Green silicon carbide (GC) is produced by petroleum coke, quality silicon sand and appended with salt in an electric arc furnace at high temperatures. The hardness is higher than synthetic corundum, but lower than diamond. Mechanical strength is higher than corundum. The materials are used to grind hard and brittle metal, non-ferrous metals like copper, brass, aluminum and magnesium, and non-metallic materials such as gem, optical glass, ceramics, etc.
