Abstract
The high temperature behaviour of natural zeolite levyne was studied by in situ SR-XRPD. Water loss induces the cation migration toward the framework to obtain a better coordination, forcing the breaking of some T-O-T bridges and the consequent formation of new bonds and of a new structure. The 8mR bidimensional channel system of levyne is absent in the new topology and hence the molecular diffusion should be partially hindered in the dehydrated form.
