As a noteworthy salt hydrate, sodium sulfate decahydrate or Glauber salt can be used as a phase change thermal energy storage material. Kinetic parameters of sodium sulfate decahydrate salt solution are evaluated experimentally. Instead of the traditional polythermal and isothermal methods, a novel constant temperature experimental method (based on the turbidity titration) was adopted to experimentally illustrate the induction time and metastable zone width, in unseeded batch crystallization for sodium sulfate decahydrate salt solution at different temperatures (7, 9, 10, 13, 16, 19, 22 °C) and supersaturation ratio (1.01–1.43). We determined crystallization thermodynamics parameters, solubility, and supersolubility, of sodium sulfate decahydrate salt solution under atmospheric pressure and at different temperatures. The solubility data could be well fitted by the solubility carve of sodium sulfate decahydrate in the phase diagram of sodium sulfate. Statistical analysis shows that there was consistency in the result data of solubility. Two models, classical nucleation theory (primary homogeneous) and secondary nucleation, were employed to analyze the experimental data. The secondary nucleation model helped determine the order of nucleation and nucleation kinetic constants.

作为值得注意的盐水合物，硫酸钠十水合物或芒硝可以用作相变储热材料。实验评估了硫酸钠十水合物盐溶液的动力学参数。代替传统的多热和等温方法，采用新颖的恒温实验方法（基于浊度滴定法）以实验方式说明了在不同温度下无水硫酸钠十水合物盐溶液的分批结晶中的诱导时间和亚稳区宽度（7） ，9、10、13、16、19、22°C）和过饱和率（1.01–1.43）。我们确定了在大气压力和不同温度下十水合硫酸钠盐溶液的结晶热力学参数，溶解度和超溶解度。硫酸钠相图中的十水合硫酸钠溶解度雕刻可以很好地拟合溶解度数据。统计分析表明，溶解度结果数据具有一致性。采用经典成核理论（一次均相）和二次成核两个模型来分析实验数据。二次成核模型有助于确定成核顺序和成核动力学常数。
