“…is the molar volume of pure liquid MX 3 at a given temperature taken from the compilation of Janz et al, [20] r M 3þ and r X À are the ionic radii of M 3+ and X -(for an octahedral geometry) taken from the compilation of Shannon, [21] and N Av is AvogadroÕs number. Similarly, the effective ionic radius r eff MX 2 ðM 2þ Þ of M 2+ in pure liquid MX 2 is defined as where V MX 2 m is the molar volume of pure liquid MX 2 at a given temperature taken from the compilation of Janz et al, and r M 2þ is the ionic radius of M 2+ (for an octahedral geometry) taken from the compilation of Shannon.…”

A theoretical model for the density of multicomponent inorganic liquids based on the modified quasichemical model has been presented in a previous article. In the present article, this model is applied to the NaF-AlF 3 -CaF 2 -Al 2 O 3 electrolyte. By introducing in the Gibbs energy of the liquid phase, temperature-dependent molar volume expressions for the pure fluorides and oxides, and pressure-dependent excess parameters for the binary (and sometimes higher-order) interactions, it is possible to reproduce, and eventually predict, the molar volume and the density of the multicomponent liquid phase using standard interpolation methods. All available density data for the NaF-AlF 3 -CaF 2 -Al 2 O 3 liquid were collected and critically evaluated, and optimized pressure-dependent model parameters have been found. This new volumetric model can be used with Gibbs energy minimization software, to calculate the molar volume and the density of cryolite-based melts used for the electroreduction of alumina in Hall-He´roult cells.

Evaluated data for the four properties, density, surface tension, viscosity, and electrical conductance are reported for salt systems in which both the anionic and cationic species may differ. This contrasts with the systems in the preceding publications in this series in which the anionic species were, in general, the same in the binary mixtures. The results are reported in equation form, with brief tables of numerical· values. A cross index by salt system was compiled and is included for ease of accessing the data tables.

“…The first measurements of T m of LiI brought to our attention were conducted by Janz [17] and Janz et al [18]. These authors published a T m value of about 722 K. After repetition of the measurements more than 10 years later, the same principal investigator-Janz et al [19]-reported a T m value of about (742 ± 3) K, which differs by 20 K from the previous one.…”

Experimental determination of the thermophysical properties (thermal and electrical conductivity, viscosity, and surface tension) of lithium iodide was carried out in the temperature range starting slightly above the melting point and extending to about 950 K. These measurements are motivated by the search for a transparent substance, the Prandtl number Pr of which approaches or is even less than unity, and which shows a stable Marangoni effect with respect to potential contamination of the melt. Such a combination of material properties is mandatory in the attempt of physical modeling of laser welding processes where optical access to the bulk of the fluid is needed to measure the flow field. In an extension to these basic studies, the electrical conductivity and the influence of the admixture of other iodides on Pr was also studied.
