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.
