Based on the observation of aggregate patterns of NiSO4•6H2O (retgersite) formed in aqueous solution, the crystallography relationship between crystallites in the aggregates is analyzed and crystallographic model of aggregates is built. In this model, developed simple forms {110} and {114} or {103} and {100} are connected through co-lattice net {102} and {112}, respectively. The similarity between branch-like morphology formed by this model and the feature of real aggregates and the rational index co-lattice net represent the rationality of this model.

Key words: NiSO4•6H2O, retgersite, aggregate pattern, crystallographic model
