Abstract: A phase diagram of Li₃AlF₆-CaF₂ was constructed for the concn. range 0 to 60.0 mole % CaF₂ by using thermal and x-ray phase analyses. This is a simple eutectic system with the eutectic point at 56.5 mole % Li₃AlF₆ and 43.5 mole % CaF₂ and m.p. 703°. A liquidus of the system was calcd. according to the Temkin ideal soln. model and according to the Schroeder-LeChatelier equation. The compn. of the eutectic point of the binary system Li₃AlF₆-CaF , calcd. according to the Temkin model (55.0 mole % Li3AlF6) compares favorably with the exptl. results. The calcd. value of the eutectic temp. of crystn. is 635°.
