摘要：The carbonate slats of Ca(II), Sr(II), and Ba(II), respectively, were synthesized by a new simple and cheapmaterials via the chemical reaction of an aqueous solutions of metal chloride ions (CaCl2, SrCl2 and BaCl2), potassiumiodide and urea with molar ratio 1:2:10, respectively, at ~ 100 oC for 3 hrs. The infrared spectra of the results indicateabsence of the essential bands of urea, but existed of the characteristic bands of ionic carbonate, CO32–. An importantchemical mechanisms discussed the preparation of Ca(II), Sr(II), and Ba(II) carbonate compounds were suggested.
