| Abstract: | The impurity of Ca2+Sr2+was eliminated by mixed solvent method,and BaCI22H2O of high purity was prepared from the indastrial material. The highly pure BaCI22H2O reacted with NH4HCO3 and NH3H2O.The obtained BaCO3 was insed by the secondary distilled water at 60and dried at 120.BaCO3 of high purity of 99.91% was achieved .The content of Ca2+and Sr2+ was less than 20ppm |
