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).Other polylypes with rhornbohedral unit cell: 21R-SiC 24R-SiC, 27R-SiC etc.

Acheson Process | SpringerLink
Abstract. Silicon carbide (SiC) is not uncommonly referred to as ‘carborundum’. This vernacular term commemorates a word coined by Edward G. Acheson in 1892 to describe crystals that he made in an experiment which had the real goal of making a diamond-like …
Silicon carbide (SiC) has found use in a variety of commercial appliions. Historically, SiC has been used most frequently in the metallurical, abrasive, and refactory industries. More recently, this material has found increased use in high technology appliions (e.g. electronics, aerospace, automotive, etc.).

Silicon - Wikipedia
Silicon is a chemical element with the syol Si and atomic nuer 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor.It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not

Carbure de silicium (SiC), également connu sous le nom de carborundum, est un composé de silicium et de carbone avec une formule chimique SiC. Il se produit dans la nature comme la moissanite minérale extrêmement rare. La poudre de carbure de silicium synthétique a été produite en série depuis 1893 pour être utilisée comme abrasif.
Rock Tuler Grit and Silicon Carbide Grit Kits
It is an ungraded 150/220 mesh silicon carbide powder. We use about two level tablespoons per pound of rock in a rotary tuler and about 1/2 level tablespoon per pound of rock in a vibratory tuler. Caution: Do not dispose of used grit, polish or rock slurry down a drain. Fine Rock Tuler Grit (500F Silicon Carbide) Also known as "pre-polish"

What is Rock Tuler Grit?
Most of the tuling done in a rotary tuler follows a four-step tuling process. The grits used are typically coarse (60/90 grit), medium (150/220 grit), fine (500 grit), and a rock polish such as TXP aluminum oxide. Most of the tuling done in vibratory tulers follows a three-step process that includes medium (150/220 grit), fine (500 grit), and a rock polish such as #61 Rapid Polish.
What is the difference between silicium and silicon
Silicium is a synonym of silicon. As nouns the difference between silicium and silicon is that silicium is (obsolete) the non-metallic chemical element silicon while silicon is (chemistry) a nonmetallic element (syol si) with an atomic nuer of 14 and atomic weight of 280855.
