In order to prepare a better morphology of calcium carbonate microspheres, calcium chloride and sodium carbonate were used as raw materials, and two different ways were used to prepared calcium carbonate microspheres. The products were characterized by Field emission scanning electron microscope,X-ray diffraction and Fourier transform infrared spectroscopy.Results show that under the control of the volume fraction of 50%ethanol and 1.0 mol/L citric acid solution can prepared good morphology of calcium carbo...
