Experimental Data on Solubility of the Two Calcium Sulfates Gypsum and Anhydrite in Aqueous Solutions

Calcium sulfate exists in three forms, namely dihydrate or gypsum (CaSO4·2H2O), anhydrite (CaSO4), and hemihydrate bassanite (CaSO4·0.5H2O) depending on temperature, pressure, pH, formation conditions. The of calcium sulfates occurs widely nature many engineering settings. Herein, a dataset containing the experimental solubility data minerals, i.e., anhydrite, aqueous solutions is presented. compiled contains values extracted from 42 papers published between 1906 2019. can be used for various scientific purposes such as environmental applications (e.g., gas treatment, wastewater chemical disposal), geotechnical clay-sulfate rock swelling), separation processes crystallization, extractive distillation, seawater desalination), electrochemical corrosion electrolysis).
