摘要
钡、锶属于同族元素,性质相似,分离困难。采用混合溶剂对氯化钡进行精制。精制后的氯化钡与二氧化碳、氨的混合气体反应,制得纯度达99.99%的高纯碳酸钡。
Barium and strontium belong to one family,they were some alike in nature and difficult to be separated. The mixture agents were adopted to refine for barium chloride,then barium chloride was reacted with the mixture gas of ammonia and carbon dioxide,the barium carbonate with purity of 99. 99% was prepared.
