Abstract
The corrosion of SiC in molten FLiNaK (46.5Â mol% LiF, 11.5Â mol% NaF and 42Â mol% KF) salt was studied. Results reveal that oxygen impurities from SiC and salt can affect the corrosion. SiC with a large amount of oxygen impurity is corroded, whereas high purity SiC is only slightly corroded. SiC can react with oxygen impurity in salt to form oxide and then corroded by the cleavage of SiOSi bond. Corrosion decreases the Si content in SiC, resulting in formation of a carbon-rich surface. A portion of excess C reacts with F to form CF bonds.
