炭化ケイ素とは?
Silicon carbide (SiC) is a hard chemical compound of silicon and carbon. Commonly referred to as carborundum, it occurs naturally as the rare mineral moissanite and has been manufactured as powder or crystal since 1893 for use as an abrasive. Industrially produced by the Acheson process in which pure silica sand and ground coke are heated together at high temperatures to form yellow to green to bluish-black crystals that sublimate with decomposition at 2700degC and have a density of 3.21g/cm3. Thermodynamics Silicon carbide (SiC), is an alloy composed of pure silicon and carbon that is commonly manufactured as an abrasive and in ceramics for use as an abrasive. While naturally …
