摘　　要：研究了BaF2-CaF2-CaCl2三元系电解质体系的物理化学性质,为熔盐电解法制备Al-Ca合金奠定基础.采用阿基米德法,测定了BaF2-CaF2-CaCl2体系的密度;采用差热-热重分析法,测定了BaF2-CaF2-CaCl2体系初晶温度;采用连续变化电导池常数（CVCC）法,测定了BaF2-CaF2-CaCl2体系的电导率;采用循环伏安法研究了该体系的电化学行为.The physicochemical properties of BaF2-CaF2-CaCl2 molten salt system,which acted as the electrolyte for preparing Al-Ca alloy,were studied systematically.The densities of BaF2-CaF2-CaCl2 electrolysis system were determined by Copula method.The crystallized temperature of the systems was measured by DTA.And the electrical conductivity of the system was measured by the continuously varying cell constant（CVCC） technique.The corresponding electrochemical behavior of BaF2-CaF2-CaCl2 system was studied by cyclic voltammetry.
