Silicon carbide (SiC) is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Depending on the exact reaction conditions the resulting silicon carbide is either a fine powder or a bonded mass that requires crushing and milling to produce a usable feedstock.
Silicon-carbide Diodes (SiC) - STMicroelectronics
ST’s silicon-carbide diodes take advantage of SiC’s superior physical characteristics over Si, with 4 times better dynamic characteristics and 15% less forward voltage, VF. Their low reverse recovery characteristics make ST’s silicon-carbide diodes a key contributor

Growth of beta-silicon carbide whiskers by the VLS process
Beta-silicon carbide whiskers are being grown by a vapour-liquid-solid (VLS) process which produces a very high purity, high strength single crystal fibre about 6/~m in diam- eter and 5-100 mm long. Details of the growth process are given1.
Silicon Carbide: a Love-Hate Relationship | EE Times
Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
