Preparation of Cs2ZrO3 and Cs2ThO3 Through Sol-gel Method and Their Characterization

Cesium zirconate and cesium thorate were prepared by sol-gel method following citrate-nitrate route. The compounds were characterized by X-ray diffraction, chemical analysis and simultaneous TG-DTA. The methods of preparation of Cs₂ZrO₃ and Cs₂ThO₃ reported in literature involve difficult steps and require stringent experimental conditions for obtaining the compounds. In this work we report an easier method for the preparation of these compounds at relatively low temperature. This revised version was published online in July 2006 with corrections to the Cover Date.
