溴化铯制备

主要有用氢溴酸中和碳酸铯；在过氧化氢存在下，用氢溴酸处理碘化铯，在水中重结晶等。

较常用的方法是，取16.17g硫酸铯和14.36g溴化钡(稍过量)混合，加水并加热。过滤，将滤液蒸发至干，用水处理红热的残渣，再结晶。将得到的小晶粒置于硫酸真空干燥器中保存。

还有一种制得纯品的办法，是把含铯的铝矾溶于水，用氨水转化成硫酸铯，趁热过滤除去铝。硫酸盐加稍过量氢氧化钡放置，通二氧化碳使过量钡沉淀，放置过夜使硫酸钡和碳酸钡沉淀完全。过滤，将含氢氧化铯的滤液承接入铂皿，用氢溴酸中和。重结晶即得溴化铯纯品。将此纯白色溴化铯在150℃热8h，溶于水，用纯浓氢溴酸沉淀,过滤。在氮氛或溴化氢气氛下熔融，于纯氮气中冷却，保存于氢氧化钾的干燥器中。
