A Feasibility Study of Inorganic Oxide-Fluoride Compositions for Thermal Energy Storage Applications.

Abstract

The purpose of this present investigation was to review the liquid-solid transformations of chemical compositions intermediate between pure inorganic fluorides and pure inorganic oxides. The liquid-solid tranformations of seventy oxide-fluoride systems were reviewed. Five of these oxide-fluoride systems were identified which have liquid-solid transformations in the desired temperature interval. The values of the enthalpy of the liquid-solid transformation, the eutectic temperature, the thermal diffusivity, and the density of the liquid and solid phases were measured. These measured values were compared to the values which had been measured on inorganic eutectic fluorides. As a result of this comparison, the LiF-MgF2-KF eutectic composition is recommended for thermal energy storage application because of the larger value for the enthalpy of transformation. (Author)
