Summary

Corrosion reactions between SiC ceramics and molten sodium carbonate were studied using analytical scanning transmission electron microscopy. Thin film studies were used to identify interfacial reactions and compositions of corrosion scales. Thin foils were made from SiC samples before and after corrosion in NaCO, at 1000°C for exposure times of 5 min to 48 h. Sodium silicate glass and clusters of silica platelets were found near the corrosion interfaces.
