Abstract:
By the use of TG—MS, the thermal dissociation of anhydrous CuSO4 and Al2(S04)3 was found to proceed according to the reactions: followed by the reactions: No SO3 was indicated in the dissociation of alunite. The sulfate ion appears to dissociate by at least two different mechanisms although the parameter which controls the mechanisms has not been elucidated.
