| Abstract: | Fasciculate and flower-like strontium carbonate is successfully synthesized by a simple complexing reaction and homogeneous precipitation method with the raw materials, such sa strontium chloride,urea,sodium hydroxide, starch and ethylenediamineteraacetic acid disodium salt. The sample of product was analyzed by X-ray powder diffraction, scanning electron microscopy and the infrared. This research reveals that ethylenediamineterraacetic acid disodium salt and starch play important roles in determining the final produc morphology and can form submicron fasciculate and flower-like particles, which has better dispersion property and higher purity. |
