Abstract: The data from 75 known phase diagrams of MX-M'X (X=F, Cl, Br, I; M and M' are monovalent metals) systems were processed by using the support vector machine-atomic parameter pattern recognition method. The regularity of the formation of solid solution in these systems was found. The mathematical model obtained predicted that the CsF-RbF system should form solid solution. The phase diagram of the CsF-RbF system was determined using differential thermal analysis. The results indicated that there was no temperature minimumeither in the solidus or in the liquidus and confirmed that the phase diagram was belonged to the continuous solid solubility system, which was in agreement with the computerized results of thermodynamics in the reference.

Key words: Phase diagram, DTA, CsF-RbF, Solid solubility
