The glass transition temperature (T_g) is a parameter used in many glass melt viscosity models as it denotes a temperature around which liquid-glass transition occurs. In this work, T_g values were measured for a series of low-activity waste (LAW) glasses using differential scanning calorimetry. These data were combined with T_g data of other waste glasses available from literature. The combined dataset, consisting of 137 data points, was used for the development of several models to estimate T_g from glass composition. When testing the number of influential components and different supervised learning methods, we demonstrated that using more than 10 components or using non-linear methods brought marginal improvement to the model accuracy. The best model predicts T_g of both LAW and high-level waste glasses with reasonable accuracy.

低活度废核玻璃的玻璃化转变温度

玻璃化转变温度 ( T _g ) 是许多玻璃熔体粘度模型中使用的参数，因为它表示发生液体-玻璃化转变的温度。在这项工作中，使用差示扫描量热法测量了一系列低活性废 (LAW) 玻璃的T _{g值。这些数据与}文献中提供的其他废玻璃的Tg数据相结合。由 137 个数据点组成的组合数据集用于开发多个模型以估计T _g从玻璃成分。在测试有影响的组件数量和不同的监督学习方法时，我们证明了使用超过 10 个组件或使用非线性方法对模型精度带来边际改进。最好的模型以合理的精度预测_LAW和高级废玻璃的Tg 。
