摘要：
The liquidus surface of the CaF2-CaCl2-CaSO4 system has been investigated by differential thermal analysis. Two invariant equilibria (one eutectic and one peritectic) are realized in the system. The eutectic and peritectic melt at 597 and 703A degrees C, and the enthalpies of phase transitions are 206 and 378.1 kJ/kg, respectively. Investigation of the ternary system formed by the natural minerals fluorite (CaF2), anhydrite (CaSO4), and calcium chloride (a relatively low-melting inorganic solvent) is undertaken with the goal of developing power-intensive heat-accumulating phase-transition materials and electrolytes of diversified application.
