Corrosion of Si, C, and SiC in molten salt - ScienceDirect

2019/1/1· Corrosion mechanism of SiC in molten salt In the above thermodynamic calculations, we found that corrosion of SiC in fluoride salts dissolution proceeds by dissolution of Si species. However, it remains to be determined by what mechanism Si can preferentially dissolve from a binary covalent material such as SiC and whether this mechanism is kinetically accessible to typical experiments.
