摘要：

The ionic conductivity of pressed pellets of dehydrated synthetic offretite, cancrinite and zeolite A, with various alkali metal ions, was determined by low-frequency impedance spectroscopy. Experiments were carried out in the frequency range 10 Hz-10 MHz at temperatures from 100-600-degrees-C. The conduction activation energies range between 55 kJ mol-1 (Na-zeolite A) and 108 kJ mol-1 (Li-cancrinite). The best conductivity value obtained was that of Na-zeolite A with 2.9 x 10(-3) OMEGA-1 cm-1 at 600-degrees-C.
