X-ray phase analysis in leucite systems

Original language description

X-ray powder diffraction analysis was used to determine quantitatively the amount of cubic and tetragonal form of hydrothermally prepared Cs ion-exchanged leucite. X-ray powder patterns exhibit severe overlap of reflections of both mentioned phases due to very similar unit cell parameters. Therefore Rietveld analysis occurred to be the best method to achieve this aim. Furthermore the concentration of Cs - ions present in both forms were elucidated from refinement of mixed sites occupations and precise unit cell parameters. Particle size and morphology analyses were completed by scanning electron microscopy (SEM, Philips XL 30 CP). It was proved that Cs-leucite prepared by the hydrothermal syntheses is formed by spherolites having particle size of 2 ?m,that consist of particles in tens of nm scale as the result of X-ray line broadening analysis.
