【Abstract】 Calcium carbonate is one of the main inorganic systems of biological mineralization. The study of its mineralization mechanism can provide theoretical basis and new synthesis path for bionic synthesis of new materials. In this study,sucrose and magnesium ions were used as additives to study their regulation effects on the synthesis process of calcium carbonate,and the experimental results were characterized by scanning electron microscopy( SEM),Fourier infrared spectrometer( ft-ir),X-ray diffraction( XRD) and synchronous thermal analyzer. The results show that sucrose can induce schist formation. Magnesium ions can inhibit the formation of calcite and induce the formation of fusiform aragonite. In cooperation with sucrose and magnesium ions,dendritic and flaky aragonite are induced.更多还原
