Thermal decomposition studies of the oxalate-hydrates of lanthanum, praseodymium, and neodymium on a Stanton thermobalance showed that these form a group, giving stable intermediate products (basic carbonates) before final decomposition to the oxide. Intermediate weight levels corresponding to lower hydrates were not obtained. The final stage of dehydration of these oxalates was followed by rapid decomposition, indicating that the anhydrous oxalates are unstable. The mechanism of decomposition of lanthanum oxalate was investigated in detail. A modified decomposition procedure on the thermobaiance showed that anhydrous lanthanum oxalate is fairly stable at 300 deg C. (auth)
