Silicon carbide

Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A semiconductor,it occurs in nature as the extremely rare mineral moissanite,but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .Silicon carbide (commonly referred to by its chemical formulation of SiC) is a chemical compound comprised of silicon and carbon that results in extremely hard (9 on the Mohs scale) iridescent crystals.

SE SiC Material Supplier Saint-Gobain

Hexoloy ® SE SiC is produced by the pressure-less sintering of submicron silicon carbide powder in a proprietary extruding process. The sintering process results in a self-bonded, single phase, fine grained (less than 10 μm) SiC product. Customized Hexoloy ® SE SiC extruded components can supplied to meet customer specifications.The crystal structure of silicon carbide is divided into hexagonal or rhombohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC What Is The Difference Between Alpha SiC And Beta SiC In Silicon
