炭化ケイ素の構造
Silicon carbide (SiC) is an ultrahard synthetic material first synthesized in 1891 by Edward Acheson in a furnace heated with carbon and alumina. Since its release into industry as an industrial abrasive in the 1920s, SiC has quickly become one of the most sought-after materials on a large scale. SiC comes in various crystal structures known as polytypes; for high power applications, 4H-SiC hexagonal atomic structure polytype is best. Physical Properties Silicon carbide is a fine ceramic with diverse physical properties that makes it one of the most versatile refractory materials on the market. From its strength, hardness, corrosion resistance and high melting point to its versatility in extreme engineering […]
