The high sublimation temperature of SiC (somewhere around 2,seven hundred °C) makes it useful for bearings and furnace parts. Silicon carbide would not melt but commences to sublimate around 2,seven hundred °C like graphite, having an considerable vapor stress in the vicinity of that temperature. It is also remarkably inert https://beauxxwvs.thezenweb.com/silicon-carbide-substrate-an-overview-72412855
