一水硫酸锂动力学参数的热分析研究

Thermal Analysis of Kinetic Parameters for Lithium Sulfate Monohydrate

用热分析技术研究了一水硫酸锂脱水及固 固相变的动力学参数 ,计算了一水硫酸锂脱水及固 固相变过程的表观活化能和反应级数 ,并对几种热分析处理动力学数据的方法进行了比较 ,结果表明几种方法所得结论基本一致。

Kinetic parameters and solid-solid transition of the thermal dehydration of lithium sulfate monohydrate were investigated, and the activation energy and reaction orders of both processes were determined by DTA TGA curves. Result showed that four used methods were coincident.
