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.

An international team of researchers led by David Awschalom of the University of Chicago, Illinois, has managed to polarize nuclear spins in silicon carbide (SiC) using optical light . This is not the first time this sort of spin control has been demonstrated, but compared to previous materials, SiC has many practical advantages, such as
Silicon carbide in electric vehicles stands for more efficiency, higher power density and performance. Particularly with an 800 V battery system and a large battery capacity, silicon carbide leads to a higher efficiency in inverters and thus enables longer ranges or lower battery costs.
Like all semiconductors, silicon carbide (SiC) and gallium nitride (GaN) have an energy gap separating the electron energy levels that are normally filled with electrons from those that are normally empty of electrons. Both SiC and GaN have high bond strengths, making them suitable for high-temperature appliions. Their wide band gaps also permit a nuer of novel appliions for the
