Influence of adsorbed water on the dielectric response of a ceramic material

摘要: The dielectric response of a porous ceramic has been measured in the frequency range 10–2–105 Hz and temperature 290–900 K when both dry exposed to water. These measurements have allowed dependence susceptibility its magnitude characteristic be determined. In all cases an anomalous low-frequency dispersion observed substantial differences found between sample containing adsorbed quantitative upon water content determined, tentative explanation behaviour is presented terms imperfect transport within adsorbate system. applicability this model other types dielectrically active system which contain species outlined.
