Silicon carbide is an incredible material with remarkable physical, thermal, and chemical properties that make it suitable for use in demanding environments. Edward Goodrich Acheson first synthesized graphite in 1891 during an experiment to produce synthetic diamonds, and it remains one of the hardest naturally occurring substances today. Hardness Silicon carbide’s hardness is one of its key properties and results from the covalent bonding between carbon and silicon atoms within its crystal lattice, giving this material exceptional shear and impact resistance. Furthermore, its relatively lower density compared to diamond and tungsten carbide makes handling it for cutting or grinding simple. SiC hardness can be measured using Mohs, Vickers and Brinell …
