| 摘 要： | The new technology to produce high purity SrCO_3 by with industry carbonate,hydrochloric acid, vitriol, sodium hydroxide as raw materials is investigated. The Sr(OH)_2 is mainly purified by crystallization separatingmethod. The authors Use ammonium bicarbonate in the reaction of carbonation, the high purity SrCO_3 is produced under the ultrasonic action. The solution concentration of Sr(OH)_2 and reaction temperature have important effects on the reaction of carbonation. The results show that the purification of Sr(OH)_2 is 99.78%; The paratcles of the high purity SrCO_3 distribute equably and the average particle size is small. The light concentration and te low temperature can enhance the ultrasonic cavitating reaction, and then the physical and chemical characteristics of it is improved.
