FAQs - Frequently Asked Questions about Silicon …

Silicon carbide, in its pure form, behaves as an electrical insulator. However, with the controlled addition of impurities or doping agents, and because SiC has the necessary resistivity, it can express semi-conduction properties; in other words, as a semiconductor, it neither allows a free-flowing current nor completely repels it.
