| 摘 要： | Sm(NO_3)_3·6H_2O热分解过程的研究工作虽有文献报道,但结果不尽相同。文献2]不同于文献1,3],认为分解过程中存在无水盐阶段;文献3]不同于文献1,2],认为分解过程中存在低水合物。而且文献尚缺低水合物热分解机理的报道。我们也曾做过一些工作,但脱水阶段也不详尽。为此,我们详细地研究了Sm(NO_3)_3·nH_2O(n=

| Abstract: | The thermal decomposition of Sm(NO3) 3.nH2O(n=6,5,4) has been studied with TG-DTG. The reactants, intermediates and end-products have also been characterized by IR.In addition,the apparent activation energies of dehydration were calculated with Kissinger method by means of TG-DTG curves at various step-up temperature rates and the enthalpies of dehydration were found by DSC. |
