· Since the adequate methods to incorporate the PCMs in gypsum are suspension and vacuum impregnation, their thermal properties, together with density and viscosity, need to be considered, properties that are not typically reported in the datasheets of commercial PCMs. Furthermore, the temperature dependence of the viscosity and density of the solid/liquid PCMs were .
Phosphogypsum
Synthetic gypsum, namely FGD (flue gas desulfurization) gypsum – a byproduct of coalfired energy production – is already widely accepted as a replacement for natural gypsum in many settings, including use as a soil amendment, in glass manufacturing, cement products, and more. This not only provides a readily available, costeffective alternative to mined sources of gypsum, but it also ...

Gypsum Mineral | Uses and Properties
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
