Popis:	The influence of the defect concentration on the ionic conductivity of solid solutions of high sodium sulfate (Na 2 SO 4 I) is presented. For Na 2 SO 4 Y 2 (SO 4 ) 3 solid solutions with up to 23 % defects the temperature dependence of the ionic conductivity was determined using the impedance method. The results show that the conductivity is strongly correlated to the cation defect concentration and exhibits its maximum at 7 % defects. Charge transport is performed by Na-ions. The activation energy for the ionic transport mechanism (1.1 eV) is shown to be independent of the defect concentration.
