Silicon Carbide Sponge
Silicon carbide (SiC), more commonly referred to as corundum or carborundum, is a hard chemical compound composed of silicon and carbon found naturally in moissanite minerals; however, commercial production began around 1893 for use as abrasives and bulletproof vest ceramic plates. SiC semiconductors feature wide bandgap, allowing them to operate at higher temperatures, voltages and frequencies than silicon devices and therefore handle more power efficiently. Hardness Silicon carbide is one of the hardest materials known to man, only rivaled by diamond in terms of hardness. Although not quite as hard as diamond, its Vickers hardness ranges between 3100-3200kg/mm2. As such, silicon carbide resists abrasion and thermal shock in harsh environments …
