Keywords: | Ceramic composites;Hexacelsian;Phase transformations;Zeolites | Issue Date: | 1-Jan-2005 | Journal: | Materials Science Forum | Abstract: | A series of hexacelsians with different compositions were synthesized by thermally induced transformation of a LTA zeolite. Various forms of hexacelsians have been characterized by XRPD, IR, Raman and 29Si MAS NMR method. The phase transformation α→β hexacelsian was investigated by DSC method. This phase transformation is sensitive to synthesis conditions, doping and thermal treatment. The peak maximum temperature, Tm, varies from 302 up to 353 °C. Heat of transformation changes from 0.42 to 1.77 kJ/mol. |
