SiC exists in nature as the extremely rare mineral called moissanite, while most of this material is synthesized in factories. As SiC is extremely hard, It has been mass produced as abrasive since late 19th century. Silicon carbide powder has a black color when the
Use the molar mass of silicon carbide to determine how many moles were actually produced by the reaction - do not forget to convert the mass of silicon carbide from kilograms to grams by using the conversion factor "1 kg" = 10^3"g" 30.0 color(red)(cancel(color
β-silicon carbide which is optically transmitting in the visible and infrared regions is produced by chemical vapor deposition. Deposition conditions are temperatures within a 1400-1500 C range, pressure 6.7kPa or less, H₂/methyltrichlorosilane molar ratios of 4:-30: 1
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
The predominance diagrams of the Si-C-O system for 1350 to 2200 C have been constructed thermodynamically by taking into account the presence of liquid silicon monoxide. The high-temperature behavior of various feeds, such as the SiO 2-C and SiO 2-SiC systems, have been calculated as functions of mixing ratio and reaction temperature by using the method of equilibrium mass-balance.
