Volumetric Properties of Molten Salt Hydrates

Abstract

The densities ρ of molten salt hydrates C p A q •nH 2 O were obtained from the literature over a range of temperatures. The values of ρ and the pertinent isothermal expansibilities α P and molar volumes at the corresponding temperature of 1.1 times the melting point (T m /K) are tabulated. The molar volumes of the melts are discussed in terms of the electrostriction of the water.

“…On the other hand, they appear noticeably larger (by 23 %) than their alkaline nitrate salt counterparts such as sodium nitrate (NaNO 3 ) which hold a density of 1.182 g cm −3 for a concentration of 4 mol kg −1 at 25 °C [29] . The S1–S4 solutions appear dense and structured as the salt concentration increases, which is logical for divalent salts [30] . All exhibit a monotonic variation of density with temperature (Figure 1c), with a thermal expansion coefficient of ca.…”

“…[29] The S1-S4 solutions appear dense and structured as the salt concentration increases, which is logical for divalent salts. [30] All exhibit a monotonic variation of density with temperature (Figure 1c), with a thermal expansion coefficient of ca. À 3.9 � 0.2 10 À 4 K À 1 , lower than the one for water (i. e., À 6.70 10 À 4 K À 1 ) and pure hexahydrate salt (À 5.5 � 0.2 10…”

Low-Melting Ionic Salts

“…where r i are the crystal ionic radii, and for some of the polyatomic ions they are given in [75,76]. The molar volume of water at the corresponding temperature T ¼ 1.1T m is calculated from its expansibility as:…”

“…This proposed sequence of events would be part of the general phenomenon we describe as EIWS. Recent empirical data of Marcus, indicating that Al 3+ has an endergonic effect on interfacial water tension [200,235], provides substantial support for the EIWS hypothesis [2].…”
