In this work, the temperature dependent electret state (ES) effect on the resistivity of microporous clinoptilolite was studied. The current-voltage characteristics with an unusual hysteresis in the clinoptilolite wafers were measured for different temperatures in the range of 30-260 degrees C. After the application of a constant electric field of 2 kV cm(-1) in air medium for 24 h, the effect of the electric field on the electrical properties of clinoptilolite wafers was investigated. A significant change in the stability of the ES was observed for clinoptilolite plates. The transport properties were restored, which confirmed the presence of the initial electret state in clinoptilolite plates at atmospheric pressure. Differences in transport properties remain for several days. It is considered that the electric field E produces a polarization inside the sample, where the carriers move through the dielectric and they are captured at the traps by resulting in a certain distribution of space charge in atmospheric pressure.
