摘　　要：作者用差热分析法及热力学计算重新测定了KF-KCl系二元相图.结果表明,在KCl一侧有少量固溶体生成,其固溶度xKF大约为0.07.该结论澄清了以前文献上存在的对KF-KCl二元体系是否存在固溶体的争论.Molten salt phase diagram of KFKCl system has been redetermined by using DTA measurement and thermodynamic calculation. Both DTA and thermodynamic calculation confirm that KF has significant solid solubility on the KCl end, and the solid solubility is approximately 0.07. The results have clarified a previous controversy over the phase diagram of KFKCl systems.
