✦ Synopsis

Ionic Conductivity Studies in Yttrium-doped KCl Crystals

Ionic conductivity measurements have been made on Potassium Chloride crystals doped with different concentrations of Yttrium, in the temperature range 200 "C to 600 "C, to understand the nature of impurity vacancy (I-V) complexes, various types of their formation and to understand how these I -V complexes affect the conduction process. The conductivity-temperature plots of KC1 : Y showed three distinct regions. These regions are explained on the basis of DRYFUS and NOWICK notation, formation and dissociation of yttrium impurity precipitates.
