Structure of synthetic zeolite Na-P2
Acta Crystallographica Section C Crystal Structure Communications, 1990Na 4 Al 4 Si 12 O 32 •14H 2 O cristallise dans Pnma avec a=9,868, b=10,082, c=10,098 A, z=1; affinement jusqu'a R=0,053. Le reseau tetraedrique de Na-P2 presente une conformation nouvelle du type flexible gismondere. Les deux parametres cristallins, presque identiques, ne correspondent pas aux axes tetragonaux topologiques du reseau ...

Xenon adsorption in synthetic chabazite zeolites
Microporous and Mesoporous Materials, 2010Abstract Xenon adsorption has been studied in different ion-exchanged forms of synthetic chabazite zeolites, K–, Ca–, Li–, Rb– and Cs–CHA, at low pressures and variable temperature. The xenon adsorption capacities vary with the nature of the exchanged cation in a way that is consistent with the known cation locations in the zeolite.

The structure of synthetic zeolite G
Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1965The sodium ions in zeolite G are not located in the openings of the six-membered oxygen windows, but are shifted toward the center of the cubic octahedral cavities.

Electrical Conductivity of Synthetic Crystalline Zeolites
The Journal of Chemical Physics, 1961The electrical conductivity of anhydrous Linde zeolite types A, X, and Y in various cationic forms has been measured between 20 and 400°C. The conductivity is ohmic, essentially noncapacitive, and appears to be strictly ionic with unusually low activation energy.

Conversion ofsec-butylbenzene over synthetic zeolites
Applied Catalysis A: General, 1994Abstract The title reaction has been studied on Y, MOR, ZSM-5 and partially dealuminated Y zeolites under standard conditions. The reaction turned out to be rather complex, involving many parallel and/or successive steps. In particular, the reactant can undergo dealkylation, isomerisation and disproportionation in various relative ratios, depending ...

Zeolite studies II. Ion-exchange properties of some synthetic zeolites
Materials Research Bulletin, 1967Abstract Studies of the calcium-strontium ion exchange properties of synthetic mordenite, clinoptilolite, ferrierite and yugawaralite show unequivocally that strontium selective zeolites can be prepared by synthesizing the zeolite in the presence of strontium.
