Abstract: The results of investigation of the temperature of primary crystallization of the system Na₃AlF₆-K₃AlF₆-Al₂O₃  are presented. The experimental data are compared with calculated temperatures of primary crystallization using the "universal model". It follows that alumina dissolved in molten  K₃AlF₆ forms another type of oxofluoride species than are those which have been reported for molten Na₃AlF₆-Al₂O₃   mixtures at comparable con­centration.
