通过离子交换法由碳酸钙制备磷酸钙

In this study, calcium carbonate microspheres were first prepared by the biomimetic method using starch as the template. Then, the calcium carbonate microspheres were converted to calcium phosphate by the ion exchange reaction at ambient conditions. Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and sizer analyzer were used to verify the succesful conversion of calcium carbonate to calcium phosphate by the ion exchange reaction.
