AI Article Synopsis

  • The study discusses the products of isothermal compressibility (κT) and surface tension (σ) in over 60 different molten salts, highlighting their relevance in the field of liquid properties.
  • The research shows that calculations using scaled particle theory and a simplified correlation theory yield values for κT and σ that are about twice as high as what experimental data reveals.
  • New correlations between κT, σ, and cohesive energy density in this study provide results that align more closely with experimental observations for a broader range of molten salts, not just the previously examined 1:1 salts.

Article Abstract

Products of the isothermal compressibility, κT, and the surface tension, σ, that have been discussed in the literature for liquids in general are shown for over 60 molten salts. The applications of the scaled particle theory of Mayer and the simplified corresponding states correlation of Harada et al. [Ind. Eng. Chem. Fund. 22, 116 (1983)] lead to calculated values twice as large as the experimental ones. Separate correlations in this paper of κT and of σ with the cohesive energy density lead to κTσ products that are commensurate with the experimental values for many of the molten salts, beyond the few 1:1 molten salts that have been dealt with previously.
