摘要
采用TG-DTG法研究了Gd(NO_3)_3·nH_2O(n=6,5,3.5)的热分解行为,通过IR对反应物、中间产物和最终产物进行了鉴定,借助不同升温速率下TG-DTG曲线,用Kissinger法计算了它们的脱水表现活化能。
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·nH3O(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.
