| dc.description.abstract | low-silica zeolitic materials like sod, can and jbw crystallized after hydrothermal transformation of kaolinite in the system na2o-al2o3-sio2-h2o at 200°c, with or without the addition of a structure-directing agent. the synthesis products were characterized by xrd, sem, ftir, 29si and 27al mas-nmr and tga. after dissolution of kaolinite in alkaline medium, co-crystallization of sod and can, likely via a metastable lta intermediate, was followed by a transformation to jbw-type structure. | |
