Silicon Carbide is a non oxide ceramic and is used in a wide range of products that must perform in thermally (high heat and heat shock) and mechanically demanding appliions. It is employed in both abrasives and wear resistant parts for its hardness; in refractories and ceramics for its resistance to heat and low thermal expansion; and in electronics for its thermal conductivity and other

These substances are extremely hard, have high melting points, and are chemically inert. For example, silicon carbide is highly resistant to chemical attack at temperatures as high as 1600 C. Because it also maintains its strength at high temperatures, silicon
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).

Products & Solutions – Super Abrasives
Diamond’s incomparable hardness and resistance to wear makes it excellent for machining hard, brittle and short-chipping materials such as carbide, glass, ferrites, GFRPs, ceramics and composites. With proper grinding parameters, diamond wheels produce lower wear event at high material removal rates, thus retaining a sharp cutting edge and more readily achieving accurate shapes and dimensions.

Super Hard Ceramics – They don’t get much tougher | …
Boron Carbide, for instance, is currently the hardest material produced in tonnage quantities and is the third hardest material known to man after diamond and cubic boron nitride. Not far behind it in the hardness stakes comes silicon carbide, more commonly known as carborundum, steeped in history since it was first mass-produced in 1893 and probably the most common of all industrial abrasives.
Diamond-coated plain bearings | KSB
Plain bearings are subject to severe wear when employed in mag-drive or canned motor pumps. The advantage of these pump types is the fact that their design prevents leakage of the fluid pumped, making them extremely environmentally friendly. Up until now, bearing components made of silicon carbide have been used; such ceramic bearings are a good choice since they are highly resistant to
