Silicon carbide (SiC) is an ultra-hard non-oxide ceramic with distinct properties and applications, first discovered in 1891 by American inventor Edward G. Acheson while trying to produce artificial diamonds. SiC is typically an insulator in its pure state but can exhibit semi-conductivity through controlled doping. A wide bandgap material like SiC can move electrical energy more efficiently than traditional semiconductors. Origin Silicon carbide (SiC) is a hard, brittle compound of carbon and silicon with the chemical formula SiC. This material occurs naturally as the mineral moissanite but has been mass produced as an abrasive since 1893. Grains of this material can be fused together using sintering to produce very hard …

Silicon carbide stones are popularly used to sharpen hard stainless steel knives quickly and aggressively due to their faster sharpening time and more durable grit that doesn’t dish easily. High carbon steels will generally not pose any problems for most stone types, including natural Arkansas stones and aluminum oxide stones; however, some steels require more specific solutions. Grit A sharpening stone’s grit rating measures its coarseness or fineness and effectiveness at creating a cutting edge. A lower grit stone will suffice for roughing out initial cuts while higher-grit stones provide greater opportunities for refining and polishing cutting edges. Green silicon carbide (GSC) is the go-to material for grinding stones. Produced …
