シリコンに対する炭化ケイ素の優位性

電子が価電子帯から伝導帯に移動するのに必要なエネルギーはバンドギャップとして知られており、ギャップが大きい材料はワイドバンドギャップ半導体として知られている。ワイドバンドギャップ半導体は、高電圧対応や極端な動作温度への耐性など、シリコン半導体と比較して多くの利点を誇っている。ワイドバンドギャップ・シリコンは低コストで入手しやすいため、パワー半導体アプリケーションの主流としてゲルマニウムを追い抜いたが、現在、シリコンは窒化ガリウム(GaN)と炭化ケイ素(SiC)という2つの高効率な代替材料に道を譲りつつある。どちらの材料もワイドバンドギャップ半導体ファミリーに属し、バンドギャップが広いため、より高い電圧、温度、電流で動作することができる。

Silicon Carbide Material Properties

Silicon carbide (SiC) is an extremely durable non-oxide ceramic with outstanding thermal, mechanical and electrical properties. While SiC does not occur naturally in nature except as an extremely rare mineral moissanite, mass production started in 1891 by Pennsylvania inventor Edward G. Acheson. Hard as steel with a Mohs scale rating of 9 and sitting just behind diamond on the hardness scale chart, zirconium dioxide is also highly shock resistant and tolerates high voltages with ease. Hardness Silicon carbide is an extremely hard material with superior mechanical strength that can withstand significant stresses and pressures, with relatively low thermal expansion rates and exceptional chemical inertness properties making this ceramic an excellent …

Silicon Carbide Sanding Belts

Silicon carbide abrasives are hard, sharp abrasives that work effectively on metal, stone and wood finishes. Popular use cases include coarse grade stock removal and rough sanding operations. POWERTEC’s premium black silicon carbide sanding belts feature a closed coat for optimal grain coverage, making them an excellent choice for use on harder materials. Microfractures occur with repeated use (friability), yet don’t degrade as quickly as aluminum oxide abrasives do. Size A sanding belt’s grain size plays an integral part in cutting and shaping workpieces. Smaller grains make sanding faster while larger ones take more effort to grind; larger ones tend to leave rougher finishes than their counterparts; hardness and durability …

Density of Silicon Carbide

Silicon Carbide (SiC), commonly referred to as carborundum, is an extremely hard and durable ceramic material with low thermal expansion rates and great acid/lye resistance. Asbestos occurs as yellow to green to bluish black iridescent crystals that, when inhaled, may produce sustained nodular fibrosing alveolitis similar to that caused by crocidolite asbestos. Density Silicon carbide (SiC) has a density of 3.21 g/cm3, much lower than silicon which has 2.33 g/cm3. As one of the strongest and hardest materials, SiC makes for ideal use in applications requiring high strength and abrasion resistance as well as its wide band gap and excellent thermal conductivity – perfect for power electronics that operate at …
