Abstract
Official abstract text for this publication.
The present invention relates to an organotemplate-free synthetic process for the production of a zeolitic material having a CHA-type framework structure comprising YO 2 , X 2 O 3 , and optionally comprising Z 2 O 5 , wherein said process comprises the steps of: (1) providing a mixture comprising one or more sources for YO 2 , one or more sources for X 2 O 3 , and seed crystals having a CHA framework structure, wherein the CHA framework structure of the seed crystals comprises YO 2 , X 2 O 3 , and optionally comprises Z 2 O 5 ; and (2) crystallizing the mixture obtained in step (1); wherein Y is a tetravalent element, X is a trivalent element, and Z is a pentavalent element, wherein optionally one or more sources for Z 2 O 5 are further provided in step (1), and wherein if the CHA framework of the seed crystals does not contain Z 2 O 5 , the seed crystals then have a YO 2 :X 2 O 3 molar ratio of 5 or greater than 5.
