Abstract: Nano?鄄sized calcium carbonate were synthesized by double decomposition method with appropriate response devices and experimental conditions and selecting Ni(NO3)3 and ZnSO4 as crystal control agents,respectively.The products were characterized by FT-IR,SEM,and XRD.Results showed that Ni(NO3)3 and ZnSO4 had a significant effect on crystallization of calcium carbonate.A variety of different shapes of particles,such as calcite,vaterite-type,and aragonite,were synthesized. The research provided experimental data for the use of additives and their effect,and also provided a viable experimental experience and ideas for such reactions.

Key words: nano-sized calcium carbonate, crystallization control, nickel nitrate, zinc sulfate
