2. The atmosphere of silicon carbide impact:

The furnace atmosphere of silicon carbide have an important effect on the service life, silicon carbide in dry clean air (1500 °C) continuous service life can reach 6000 hours. 

Silicon carbide in use process can with oxygen and water vapor happen slow response (SIC + 2 O2 = SIO2 + CO2 and H2O SIC + 4 = SIO2 + 4 H2 + CO2) make great body of SIO2 gradually increase, then the resistance increases; Under high temperature hydrogen (H2) 

Crystalline structure of SIC has damage effect; Fluorine (F2) and chlorine (Cl2) to elements are corrode action.
