Growth of Cesium Chloride Crystals from Solution and Melt

Abstract

Large cesium chloride crystals were obtained from solution only upon addition of urea. These crystals, however, show NH4+ impurity. Since CsCl undergoes a phase transition between its melting point and room temperature, normal growing methods from the melt could not be used, but a modified (``double-run'') Bridgman method yielded good results.
