ABSTRACT:
Phase diagram of the LiCl–MnCl2 binary system was studied by the method of synchronous thermal analysis. It is established that this system is characterized by the presence of a congruently melting compound Li2MnCl4 (Tm = 855 K) and two eutectics with coordinates Te1 = 829 K; x(MnCl2) = 0.525 and Te2 = 851 K; x(MnCl2) = 0.255. It was found that in the solid state the Li2MnCl4 compound undergoes a secondEorder phase transition at T = 733 K with a jump in the heat capacity Δcp = 117 J/(mol К).
