Shapton glass or pro stones? | BladeForums

20/12/2013· Silicon carbide rates on the Mohs scale as does most other abrasives which is much harder than steel. It''s actually not far off from ceramic and diamond. Vanadium carbides do great at adding wear resistance but I have sharpened steels such as S30V with Norton India and SiC stones, I''ve also sharpened it with king waterstones, its very slow going in some cases but works.

The Difference Between Lab Grown Diamonds and …

Regardless, the mineral version of silicon carbide was later named after him. As fascinating as that is, however, modern Moissanite is not actually natural. Natural samples of Moissanite are incredibly rare – aside from Moissan’s discovery only a few more have been found in other meteor craters, in the Wyoming Green River Formation, and even rarely as inclusions inside of diamonds.

Boron carbide is an extremely hard boron–carbon ceramic, and covalent material used in tank armor, bulletproof vests, engine sabotage powders, as well as numerous industrial appliions. With a Vickers Hardness of >30 GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond.

Silicon carbide — Wikipedia Republished // WIKI 2

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).
