Keywords: | Ceramics;Chemical synthesis;Crystal structure;Phase transitions | Issue Date: | 1-Jan-2008 | Journal: | Journal of Physics and Chemistry of Solids | Abstract: | The Li+- and Na+-doped hexacelsians (HC) synthesized from Ba-LTA synthetic zeolite as precursors were used for preparation of monoclinic celsians (MC). The doped pure MC and mixture HC/MC species were obtained by thermally induced polymorphous transformation at 1200 C. Synthesized-doped MC have been characterized by X-ray powder diffraction and spectroscopic (infrared, Raman and 29Si magic angle spinning nuclear magnetic resonance) methods. The obtained results suggest that in all investigated samples Na+ or Li+ dopants were incorporated in MC crystal structures during thermal transformation of a zeolite. It has been shown that HC → MC transformation depends on molar fractions of alkali cations. These findings combined with used temperature/time conditions could help in optimization of MC synthesis route. © 2008 Elsevier Ltd. All rights reserved. |
