Abstract: Temperature dependence of density of the Na₃AlF₆-K₃AlF₆-Al₂O₃ melts was investigated by the Archimedean method. On the basis of the knowledge of density of boundary systems, density of the tenary system was calculated. The agreement between experimental and calculated set of data is very good. Partial molar volumes of infinitely diluted alumina in molten Na₃AlF₆ and K₃AlF₆ are 68.49 cm³ mol^-1 and 54.77 cm³ mol^-1, respectively, at the temperature of 1000°C.
