Summary
The thermal decomposition of the anhydrous rare-earth sulfates was studied by thermogravimetric analysis (TGA) and differential thermal analysis (DTA) up to a temperature limit of 1400 deg C. TGA curves showed that the thermal decomposition reaction took piace in two steps. The first step corresponded to the formation of metal oxysulfates, M/sub 2/Ch(SO/sub 4/), the second step corresponded to the formation of the metal oxides. DTA studies also revealed this decomposition pattern, giving as evidence two endothermic peaks. The heats of decomposition to the metal oxysulfates and sulfates were determined by quantitative DTA methods. Preiiminary information was obtained on the kinetics of the decomposition reactions.
