In the previous chapters, we have considered the adsorption properties of composites “salt in porous matrix” (CSPMs). Here we survey their thermal properties, namely, heat capacity and heat conductivity. Both these values are fundamental characteristics of CSPMs and create a base for calculating their thermodynamic and dynamic performances in various applications, some of which are considered in this book. Tabulating these properties is strictly necessary for theoretical analysis of the applications, making estimations, engineering calculations, and mathematical modeling.
