摘要：The metastable zone width (MSZW) of SrCl2·6H2O during cooling crystallization was determined by the focused beam reflectance measurement (FBRM). The effects of the saturation temperature, cooling rate, stirring rate, and Ca2+ ion impurity on the MSZW were investigated. The MSZW increased with the increase in the cooling rate and decreased with the increase in the saturation temperature, stirring rate, and Ca2+ ion concentration. Moreover, the effect of seed crystals on the MSZW was investigated, where two types of seeds were used, namely, seed 1# and 2# with volume mean crystal sizes of 64 and 218 μm, respectively. The seeded MSZW decreased than the unseeded one. The MSZW of seed 1# was greater than that of seed 2# when the same amount of seed was used. The MSZW of seed 1# increased with the increase in the seed loading, whereas that of seed 2# decreased. ? 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
