Crystal Growth | Simco Groups
In spite of great technological advances in recent years, we are still at an early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT and gallium nitride. Simco is a key equipment supplier for crystal growth
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
