| Abstract Scope |
Melt point, enthalpy of fusion, heat capacity, and volumetric expansion of single- and multi-component liquid chlorides {NaCl, KCl, LiCl, MgCl2, CaCl2, UCl3} were measured experimentally. These properties and materials are relevant in applications such as heat transfer, liquid nuclear fuel, and pyrochemical processing. A novel method for density measurement by neutron radiography was shown to produce high-quality data, consistent with reference literature where available. Measurements of the melt point, enthalpy of fusion, and heat capacity of these ionic liquids were achieved by differential scanning calorimetry. All results are presented within the context of a comprehensive review of the available published data. Models for the prediction of the density and heat capacity of mixtures of liquid chlorides are proposed and demonstrated within a case study of the {NaCl + x mol% UCl3} system. |
