Abstract

The present research describes the synthesis of the citrate of Pr by the amorphous citrate method and the study of the thermal decomposition of the complex in air, nitrogen and oxygen, in order to identify the final compounds and the intermediates obtained during the decomposition. A special study was dedicated to the thermal decomposition of the Pr-carbonate octahydrate used in the synthesis as starting material. The thermal decomposition of the lanthanide citrate was investigated mainly by thermogravimetry, differential thermal analysis, X-ray diffraction and infrared spectroscopy. The results showed that the complex decomposes to PrO1.83 with formation of an intermediate oxy-carbonate compound in air or directly to the oxide in oxygen; in nitrogen atmosphere, amorphous products were obtained after thermal decomposition.
