Dataset and prediction model construction of melting enthalpy of binary molten salt systems and their performance research

Based on this, four empirical prediction models were established, namely logarithmic form (Model I), linear additive form (Model II), fractional form (Model III), and power-law form (Model IV). Furthermore, the predicted values of each model were compared with the experimental values, and the errors were calculated.

The results showed that Model III, using a fractional form, exhibited the best prediction accuracy, with a total average error of only 0.07 between the predicted and experimental values. This indicates a fractional nonlinear relationship between the melting enthalpy of mixed molten salts and their different components. Model I had the second-highest prediction accuracy, while Models II and IV had larger prediction errors compared to the former two models.
