It's Got a high chemical affinity for oxygen, and it was not discovered in its pure type until eventually 1823 by Jöns Jakob Berzelius. Other than crystal high quality, complications with the interface of SiC with silicon dioxide have hampered the development of SiC-based power MOSFETs and insulated-gate bipolar transistors. https://x.com/Anumhsite/status/1809240277137453215
