Surface tension of light rare earth fluoride molten salts electrolyte system

Studies on the Surface Adsorption of Binary Molten Salts

“…As shown in eq 6, they correspond to the transition heats per unit area (Q/A s ). The phase transition heat (Q/A s ) of the two molten mixtures increases gradually with the increase of CsNO 31 Ionic potential ϕ is usually defined as ϕ = z/r, where z and r are the ionic charge and radius, respectively. In the work of Levin et al, 22 Latimer hydration radii for halogens were used as ionic radii, which are almost identical to the Pauling crystal radii.…”

“…Hara et al 29,30 measured the surface tension of binary molten salt systems with the sessile drop method and the composition dependence on the surface tension of those systems. Zhu et al 31 Nd 3+ are higher than that of Li + , interactions between La 3+ and F − and Nd 3+ and F − are stronger than the interaction between Li + and F − . Therefore, the surface tensions of molten salts LiF−LaF 3 and LiF−NdF 3 increase with the increasing concentrations of LaF 3 and NdF 3 .…”

“…Therefore, the surface tensions of molten salts LiF−LaF 3 and LiF−NdF 3 increase with the increasing concentrations of LaF 3 and NdF 3 . 31 In our laboratory, a series of studies 23−25 have been carried out on surface adsorption of liquids. A novel thermodynamic state function was defined and was exploited to derive the surface adsorption equation of solute in solution.…”

“…Hara et al , measured the surface tension of binary molten salt systems with the sessile drop method and the composition dependence on the surface tension of those systems. Zhu et al measured the surface tensions of LiF-REF 3 (RE = La and Nd) molten salts with the Wilhelmy slide plate method and discussed with ionic potential the variation of the surface tension with the concentration of REF 3 . Because the ionic potentials of La 3+ and Nd 3+ are higher than that of Li + , interactions between La 3+ and F – and Nd 3+ and F – are stronger than the interaction between Li + and F – .…”
