Abstract
Solution mediated phase transitions in aqueous suspension (pH 9.5) of MgSO3 hydrates were studied at 50, 60, 65, and 70-degrees-C for hexa- to trihydrate and 25, 30, and 35-degrees-C for tri- to hexahydrate con version. The former conversion is controlled by the diffusion growth o f the new phase crystals whereas the latter process is controlled by b oth the initial phase dissolution and the new phase growth.
