Abstract

ac conductivity studies conducted on glasses with NASICON-type chemistry reveal many universalities in their behaviour. It is found that the total conductivity of all the glasses at all temperatures can be fitted well with a double power law using $s_1 = 0.5$ and $s_2 = 1.0$. It is found that the plots of reduced conductivity (with respect to the dc conductivity) versus reduced frequency (with respect to M peak frequency) are superimposable for all the glasses at all temperatures, indicating that the ionic conductivity in these materials is independent of a number of factors like the nature and concentration of the cation and structure of the glass.
