Pressure-induced increase of ionic conduction of water-treated NaA zeolite

Dehydrated, hydrated and superhydrated NaA zeolites have been studied by impedance spectroscopy with scanning frequency from 1 Hz to 1 MHz at high pressure up to 4.5 GPa. A considerable anomalous increase in electrical conductivity in the range of 0.5–1.1 GPa was observed in superhydrated NaA zeolit...

Beschreibung
Zusammenfassung:	Dehydrated, hydrated and superhydrated NaA zeolites have been studied by impedance spectroscopy with scanning frequency from 1 Hz to 1 MHz at high pressure up to 4.5 GPa. A considerable anomalous increase in electrical conductivity in the range of 0.5–1.1 GPa was observed in superhydrated NaA zeolite containing additional water in the channels. A very high mobility of ions in superhydrated zeolite may be associated with the liquid‐like state of the water‐cation stuffing of zeolite channels. (© 2005 WILEY‐VCH Verlag GmbH & Co.
