Abstract

Abstract : Single crystals of aluminum sulphate hexadecahydrate (Al2 (SO4 )3 16H2 O) were obtained from aqueous solution, and their hexagonal‐plate morphologies were captured with a polarizing microscope. The predicted morphology derived from the modified AE model considering solvent effect was consistent with experimental results. Abstract : A single‐crystal structure of aluminum sulfate hexadecahydrate (Al2 (SO4 )3 ·16H2 O) was captured with a polarizing microscope. The structure was similar to a hexagonal plate and consistent with the predicted morphology derived from the modified AE model. An octagonal plate morphology was first obtained in a vacuum but was transformed into hexagonal plate‐like when the effect of the solvent with two disappearing {1 1 0} and {1 0 −1} faces was considered.
