Frictional performance of silicon carbide under different …
Silicon carbide is commonly used in hard rings because of its abrasion resistance, corrosion resistance, and thermal shock resistance. In this study, the frictional performance of silicon carbide, including graphite-added silicon carbide, under water and lubriion
why is aluminum oxide used more frequently than silicon …
2007/8/2· Aluminum oxide is tougher and therefore better suited to grinding steel, and a lot of grinding is done on steel. Silicon carbide is harder, but quite brittle, it tends to break into sharp shapes which is an advantage for nonferrous and nonmetallic workpieces, but the lack of toughness makes it specialized abrasive and therefore it is used less than aluminum oxide.

Precision Polishing - Microfinishing and Lapping Film - …
Variations depend on the mineral (aluminium oxide or silicon carbide), the grit range, and the thickness of the backing film required. Diamond is the hardest mineral available, so it’s dedied to all the critical microfinishing operations that cannot be performed with the other abrasive minerals such as the finishing processes of carbides, ceramics, harder metals, stones and glass.

The same grit belts of Silicon Carbide will stain differently than Aluminum Oxide, with a lighter color gradient than when sanded with the traditional Aluminum Oxide belts. Silicon Carbide is sharper than Aluminum Oxide, and is effective at removing the “hairs” that is the result of the wood fibers being bent instead of cleanly cut by an Aluminum Oxide belt.

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).
