Abstract: The phase diagram of the system Li₃AlF₆ — KCl was studied using the ТА method and x-ray phase analysis. The investigated system was founďto be a simple eutectic quasi-binary system, the co-ordinates of the eutectic point being 25 mole % Li₃AlF_{6 +} 75 mole % KCl, t_E = 620°C. The Li₃AlF₆ liquidus curve is practically linear, whilst the liquidus curve of KCl is expressively convex with respect to the concentration axis. The course of the KCl liquidus curve enables one to assume a total destruction of  Li₃AlF₆ molecules in the range of small concentrations of lithium cryolite.
