ABSTRACT

The specific heat capacity data of unary salt measured by different experimenters have certain differences due to the different experimental conditions. This paper focuses on the study of differential scanning calorimetry for measuring the specific heat capacity of molten salt. The data measured by different experimenters will be analyzed and compared, and finally more reasonable data will be screened out. The results show that in the molten state, the specific heat of NaNO3, KNO3, and LiNO3 is almost constant. Part of the reason for the difference in the experimental values of the specific heat capacity of different experimenters is that the temperature range of the solid-liquid coexistence zone is not consistent. The filtered data of this paper can be used as the basis for predicting the specific heat capacity of the mixed molten salt.
