| Abstract: The thermal decomposition of Gd(NO3)3·nH2O(n = 6,5,3.5) has been studied with TG-DTG.The reactants, intermediates and end-products have also been characterized by IR. It was found that the rcactants underwent aseries of decomposition stages, the intermediates were lower hydrates,and basic nitrate, have not anhydrous, respectively the end-products were the gadolinium oxide.The thermal decomposition mechanism of Gd(NO3)3·nH2O(n = 6,5,3.5)have been presented. In addition, apparent active energy values of dehydration were calculated with Kissinger method by means of TG-DTG curves at different step-up temperature rates. |
