Thermal decomposition of the hydrated oxalates of the above rare earth metals was carried out on a Stanton thermobalance. The oxalates after precipitation were dried at 110° C for six hours and then used for the decomposition studies. No indications of the formation of stable lower hydrates or of intermediate basic carbonates were obtained. Weight levels corresponding to oxide formation were shown in the temperature range 690–720°C.
