    • Abstract

       

      Recent experimental studies show that the dielectric constant of lead fluoride increases rapidly as the superionic transition temperatureTc is approached. In this work the static dielectric constant (ε) is calculated theoretically for low and high temperature limits. Assuming conduction to take place through a percolation mechanism,ε is found to diverge at the threshold temperatureTth where ionic conduction starts.
