Description	X-ray powder diffraction analysis was used to determine quantitatively the amount of cubic and tetragonal forms of hydrothermally prepared Cs ion-exchanged leucite. The Xray powder patterns exhibit severe overlap of reflections, since both forms have very similar unit cell parameters. Therefore Rietveld analysis occurred to be the best method to achieve this aim. Furthermore the concentrations of Cs+ - ions present in both forms were elucidated from the refinement of mixed sites occupations and from the precise determination of the unit cell parameters. It was proved that the hydrothermally synthesised Cs - leucite is formed by spherolites having particle size of 2 mu m and consisting of crystallites in tens of nm scale as the result of X-ray line broadening analysis.
