摘要
通过对合成软钾镁矾（Ｋ２ＳＯ４·ＭｇＳＯ４·６Ｈ２Ｏ）的热分析研究，由软钾镁矾的ＴＧ、ＤＳＣ确定了脱水和分解温度，结合恒温热失重实验给出了脱水过程的热化学反应方程式及其产物的Ｘ－ｒａｙ粉末衍射结果，并得到了各脱水阶段的有关热化学反应的动力学参数ｎ、ｌｏｇＫ０和Ｅ．
The thermal behavior of synthetic schoenite (K2SO4. MgSO4. 6H,2) during heating has been studied by thermoanalysis methods. the temperatures of dehydration and decomposion of schoenite have also been determined by DTA, TG and DSC.The thermoreaction equations and the X-ray powder diffraction results of the products have been given and the corresponding kinetic parameters have also been obtained.
