Evaluation of new salt-in-matrix composite materials based on silica gel and CaCl2/SrBr2 mixtures for thermochemical heat storage applications

These data are the raw data of the isotherm at 30°C measurements that were performed on 3 composites based on silica gel and 3 different CaCl2/SrBr2 mixtures. The measurements were done on a IGAsorp device (Hiden Isochema). A preliminary drying at 200°C for 10 hours was perfomed on each sample before measuring the water vapor sorption at 30°C. These data enable us to compare the water sorption behavior of these 3 composites and show how salt mixture can modulate the water sorption behavior of single salt composites.
