摘要：

High-purity cesium is prepared by azide decomposition, a method first described by Suhrmann and Clusius in 1926. All the necessary details are given for the preparation of pure cesium azide from cesium carbonate, and for the proper control of the thermolysis to cesium in vacuo. Product purity is assessed using Guinier X-ray and atomic absorption spectroscopy. Cesium of purity 99. 998% was obtained, the contaminants being other alkali metals, further removable by distillation.
