Physicochemical Properties of the (LiF + CaF<sub>2</sub>)<sub>eut</sub> + LaF<sub>3</sub> System: Phase Equilibria, Volume Properties, Electrical Conductivity, and Surface Tension
No full textThe
physicochemical behavior of the molten system (LiF (1) + CaF<sub>2</sub> (2))<sub>eut</sub> + LaF<sub>3</sub> (3) has been studied
and the phase equilibria, density and volume properties, electrical
conductivity, and surface tension have been selected for investigation.
Well-established methods for determination of these physicochemical
properties of molten salts have been used, such as thermal analysis,
the Archimedean method of hydrostatic weighing, and the phase shift
and maximum bubble pressure methods. A significant change in all investigated
properties was detected in the region of <i>x</i><sub>3</sub> = 0.04–0.06. In regard to phase equilibria, this region is
close to and may contain the eutectic point; in volumetric properties,
the initial volume contraction (on increasing mol %) starts to reverse.
A sharp change of electrical conductivity reflects the changes in
ionic composition, and surface tension also shows different behavior
below and above this region
