Surface Tension of Molten LiF-MgF2, CaF2 and SrF2 Binary Systems

Surface tension and density of molten LiF-MgF 2 , LiF-CaF 2 and LiF-SrF 2 binary systems were measured by a maximum bubble pressure method. The composition dependence of the surface tension shows the upward curvature in these binary systems. The molar volume of the binary mixtures is represented by a simple additivity. The change in the surface tension with the composition is discussed from the thermodynamic point of view. composition dependence from the systems mentioned above. Therefore, it is quite important to accumulate the information on the composition dependence of the surface tension in those systems. In the present work, we have measured the surface tension and the density of molten LiF-MgF 2 , LiF-CaF 2 and LiF-SrF 2 binary
