The thermal decomposition of thorium(IV), uranium(IV), and the rare-earth metal(III) oxalate hydrates. Differential thermal analysis and weight-loss studies

Add time:09/01/2019    Source:sciencedirect.com

Differential thermal analysis (DTA) curves are presented for thorium, scandium, uranium (IV) and the rare-earth metal oxalate hydrates. For all of the metal oxalate hydrates, endothermic and exothermic peaks are present in the curves which are the result of dehydration, decomposition, and oxidation reactions. The DTA curves for thorium and lanthanium oxalates differ from those previously reported. A weight-loss curve is presented for the thermal decomposition of the 6- and 2-hydrates of uranium (IV) oxalate.
