Silicon Carbide (Sic) Powder

Silicon Carbide, is used due to its properties of high hardness (Mohs hardness > 9), wear resistance, its chemical inertness, high thermal conductivity, abrasion resistance, low coefficient of thermal expansion, thermal shock resistance, and strength at high temperature ranges.  Silicon Carbide also has the resistivity necessary to perform as a semiconductor material.  Because of these properties, Silicon Carbide is used in a wide range of applications and industries.   Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace.  The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.  The color difference is due to the purity of the silicon carbide.  Green SiC coloring is a result of less impurities than the Black SiC.  Metallurgical Supplies  offers both Macro and Micro grit sizing.  Our Silicon Carbide is offered in standard FEPA sizes, custom particle sizes, custom densities, and custom chemistries.
