• The dielectric properties of completely dehydrated Rb<SUB>3</SUB>Na<SUB>8</SUB>–ZK4 zeolite were studied in the range 12–2.2×10<SUP>6</SUP> Hz and 211–705 K. Two kinds of losses, relaxation and conduction, were observed. The relaxation loss in the higher-frequency region had an activation energy of 99±2 kJ mol<SUP>−1</SUP> and was tentatively assigned to a jump of the Rb<SUP>+</SUP> ion from an 8-ring site to a vacant 4-ring site. The loss at the lower-frequency region had an activation energy of 95±3 kJ mol<SUP>−1</SUP> and was attributed to a movement of the Rb<SUP>+</SUP> ion on the 8-ring site beyond the unit-cell dimension.
