Gas transport mechanisms and the behaviour of …

The Acheson process still remains the method of choice for the industrial production of silicon carbide. The furnace operates in an unsteady thermal regime thus making it difficult to determine the kinetics of the process. In the present study, FactSage Software was used to get an insight and verify the dominant reactions occurring during operation. Moreover, the effect of impurities on the
