Uses of Carbide | Sciencing
Silicon carbide occurs naturally, although rarely, with the molecular formula SiC. One molecule of silicon carbide is one silicon atom and one carbon atom. When grains of silicon carbide are manufactured and fused together, they form an extremely hard, durable substance that is used in specialized items like car brakes, turbine mechanics, and certain types of seals and bearings.

Silicon Carbide SiC Material Properties - Accuratus
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.

When oxidising silicon a silicon dioxide layer forms but in silicon carbide the extra carbon atom is either released as CO gas or it clumps together to form uneven oxides on the surface.” At very high temperatures however, the likelihood that CO gas is formed increases and it is thought that this will be a key breakthrough in developing the technique for producing a unifrom oxide layer.

18/9/2018· Carbothermic smelting of ores to produce metals or alloys in alternating current open/semiclosed and closed submerged arc furnaces, or in closed direct current furnaces, results in large volumes of CO-rich off-gas being generated. Most of the CO-rich off-gas is cleaned and flared on stacks, since the storing of large volumes is problematic due to the associated toxic and explosive risks
