Thyristor Control of Silicon Carbide Heaters
Silicon carbide heaters are typically controlled by thyristor power controllers (also known as SCRs or silicon controlled rectifiers) with power feedback. In power feedback mode the thyristor measures output current and voltage, takes the product of these two measurements and then regulates the power output so that it is proportional to the control input.

Superconductivity in heavily boron-doped silicon carbide
2009/1/28· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.
