摘要：

A phase diagram of the EuCl2-NaCl system was determined by differential scanning calorimetry (DSC) and the activity coefficients of EuCl2 and NaCl in this system were estimated under some assumptions. According to DSC measurement, it was found that there were two phase transitions at 1123.9 K and 1016.8 K. In order to specify the melting point of EuCl2 we did Raman spectroscopy experiments. Thus, the melting point of EuCl2 was evaluated to be 1016.8 K which was detected as the lower peak in the DSC curve. Raman spectroscopy of this system suggested that complex species were not formed clearly in the EuCl2 poor system and the estimated activity coefficients of EuCl2 also supported this suggestion.
