The large sublimation temperature of SiC (roughly two,seven hundred °C) makes it practical for bearings and furnace sections. Silicon carbide isn't going to melt but starts to sublimate around two,700 °C like graphite, having an appreciable vapor pressure in close proximity to that temperature. It is additionally very inert chemically, https://lorenzokkkhe.bloggactif.com/35669443/helping-the-others-realize-the-advantages-of-black-silicon-carbide
