We have found that the crystals of rubidium dichromate (Rb_2Cr_2O_7) grown in gelatin gel have a rich variety of morphologies such as platelike, spherulitic and diffusion-limited aggregation (DLA)-like shapes. The morphological diagram has been determined in the range of solute and gelatin concentrations from 1.0 to 4.0%, 0.1 to 7.0%, respectively. The diagram corresponds to that of potassium dichromate (K_2Cr_2O_7) which is similar to Rb_2Cr_2O_7 in the crystal structure and physico-chemical properties. However, featherlike crystals have grown in the region of the diagram where the unique helical K_2Cr_2O_7 crystals grow. We discuss the morphological changes of two kinds of dichromate crystals grown in gelatin gel.
