With aluminum chloride and calcium chloride as mixed calcium ion sources and sodium carbonate as carbonate ion sources,calcium carbonate crystals were prepared by double decomposition method in the solution.In the process,a special reaction environment was got with the complex-shaped aluminum hydroxide gel produced by aluminum ions double hydrolysis.And the morphology was affected by the environment.The obtained samples were characterized by X-ray Diffraction(XRD)and field emission scanning electron microscope(FESEM).The results indicated that aluminum chloride had a significant effect on the reaction process and morphology.With different concentration and ratios of calcium ions to aluminum ions,calcium carbonate microparticles with different shapes,such as sphere,flower and spindle,were synthesized in the changing environment of crystallization and growth.
