Abstract

The method of thermodielectrical analysis registers in its thermogram a low temperature effect (50–350°) related with the polarization of water or other sorbed phase and cationic polarization, and a high temperature effect (400–900°) which is fundamentally related with cationic conduction. In the present report with the help of the measurement of the dielectrical permittivity of powders of homoionic zeolites was shown the role of cationic polarization in the determination of the intensity of the first thermal effect registered in thermodielectrical analysis.

Zusammenfassung

Mittels thermodielektrischer Analyse kann im Thermogramm ein Niedrigtemperatureffekt (50–350°C), verbunden mit der Polarisation des Wassers oder anderer absorbierter Phasen und der kationischen Polarisation, und ein Hochtemperatureffekt (400–900°C) festgehalten werden, welcher grundlegend mit der Kationenleitung in Verbindung gebracht werden kann. In dieser Arbeit wird mittels der Messung der Dielektrizitätskonstante von homoionischen Zeolithpulvern die Rolle der kationischen Polarisierung bei der Bestimmung der Intensität des bei der thermodielektrischen Analyse registrierten ersten thermischen Effektes gezeigt.
