Thermochemical investigation of the water uptake behavior of MgSO4 hydrates in host materials with different pore size
Abstract
Influence of confinement in porous materials on hydration reactions is investigated. The heat of sorption in porous composites with MgSO4 depends on pore size. The heat of sorption increases with decreasing pore size due to higher water uptake. The final hydration product varies with pore size. Salt hydrates in porous host materials are promising heat storage materials.
