High Temperature Alloys - an overview ScienceDirect Topics

Two classes of hot corrosion are induced by pure Na 2 SO 4: type I ‘high temperature’ at temperatures within 850–1000 C and type II ‘low temperature’ at temperatures below 800 C. Sometimes accelerated or astrophic corrosion occurs in eutectic salts containing NaCl and Na 2 SO 4 .
