Dielectric response in natural clinoptilolite

Several samples of cation forms of the natural clinoptilolite from Tasajeras deposit were studied using dielectric spectrometry. The behaviour of the response was analyzed for different water contents and, for the calcium and sodium forms, it was investigated for several temperatures too. The results show the influence of cation nature and water content in the shape and magnitude of the dielectric response. Two relaxation domains appear in the frequency range from 34 Hz to 500 kHz which were studied following the formalism of the universal dielectric response in solids. The existence of correlated motions between water-induced species and cations is discussed.
