Une étude de la permittivité complexe mesurée dans une grande gamme de fréquences est présentée pour 3 types de zéolithes contenant des protons. Dans tous les cas, l’origine de la polarisation observée est interprétée par l’existence de mouvements d’ions corrélés sur des distances microscopiques. A partir de cela, il est possible d’obtenir des informations sur là cristallinité et l’homogénéité des échantillons ainsi que sur la nature des sites acides
