Abstract: The density of the melts of the system KCl-KBF4-K2TiF6 has been measured using the Archimedean method. The molar volume, the partial molar volume, and the excess molar volume of the melts at 1000, 1100, and 1200 K were calculated on the basis of the obtained density data and the possible chemical interactions of components have been considered. The dependence of the molar volume on composition was described using the regression equation V' = x1V1 + x2V2 + x3V3 + x1x3A013 + x2x3 (A023 + A123x3) + x1x2x32B The significant mutual interaction of all three components was found in the investigated system.
