Web19 okt. 2005 · Solubilities of calcium sulfate dihydrate, hemihydrate, and anhydrite in concentrated HCl, CaCl 2, and their mixed aqueous solutions were measured by using the classic isothermal dissolution method at the temperature range from (283 to 353) K. Webdration. The kinetics for calcium sulphate phases was therefore rather basically modelled, which was not sufficient for the present application. Secondly, the calcium sulphate phases were considered as source for reactions, while now calcium sulphate dihydrate (gypsum) is the final product. Thirdly, more specific properties of calcium sulphates ... infinity vision dallas tx
