FAQs - Frequently Asked Questions about Silicon …

With a hardness level of 9 on the Mohs scale, SiC is one of the hardest of the commonly used abrasives (was the hardest synthetic material until the discovery of boron nitride in 1929, which was found to have a 9.5 hardness level on the Mohs scale), despite being less resistant to impact than aluminium oxide and experiencing faster wear during grinding of metals with high affinity to carbon, such as nickel and iron.

Basic Parameters of Silicon Carbide (SiC)

Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende) ; 2H -SiC; 4H -SiC; 6H -SiC (hexagonal unit cell, wurtzile ); 15R -SiC (rhoohedral unit cell).
