    • Abstract


      The pre-exponential factors obtained from the ionic conductivity studies on Na2(La, Al)ZrP3O12, Na2(La, Al)TiP3O12, NH4Zr2V3O12 and AlPO4:Li+ have been analysed. The compensation law has been found to be valid for these materials indicating that the entropy is directly related to the activation energy. The 1/α vsβ plots show straight lines for most of the superionic materials except for a few and this variation has been discussed.
