Abstract:

The aspartic acid(Asp) was used as the inducer and candy-like calcium carbonate particles were prepared by controlling the reaction conditions such as reaction time, the dosage of inducer, and the reaction temperature, and the optimum conditions for obtaining the candy-like calcium carbonate particles were obtained. The structure, morphology and properties of the resulting calcium carbonate particles were characterized and a reasonable reaction mechanism was proposed. The new ideas about the preparation of calcium carbonate with specific morphology will be instructive in related material researches.

Key words: Calcium carbonate, Precipitation reaction, Candy-like morphology, Biomimetic synthesis
