The kinetics of the precipitation of gypsum, CaSO42H2O
2020.9.3 As the crystallization of gypsum can become a source of major technological problems during certain industrial processes, the precipitation process was studied in some simulated processes too. To characterize scaling in heat-exchangers, the crystallization of gypsum on relevant surfaces was studied by Linnikov [39, 40].
