Calcium carbide - Wikipedia
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is

Boron Carbide - an overview | ScienceDirect Topics
Boron carbide is one of the hardest ceramic materials known (see Table 7.1), falling just short of diamond and cubic boron nitride. Because of its low density (∼2520 kg/m 3), it has become the material of choice for body armour systems (Crouch, 2009).

Rock Tuler Grit – Everything You Need to Know About …
15/1/2020· It is important that silicon carbide grit is used as rock tuler grit because it has a hardness of 9 on the Mohs scale and doesn’t round out when being tuled. Because grit is so hard, as you may have noticed in your tuling, some softer materials containing different mineralization elements such as calcite may be gouged out and can give the rocks a texture.

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).-SiC (rhoohedral unit cell).
