Natural Zeolite Clinoptilolite belonging to group VII  Zeolite were obtained from the quarries near Ajanta caves, Marathwada (Maharashtra). Characterization was made using XRD,IR at NCL Pune. Dielectric study was made using LCR Bridge. Pellets of NH4 Clinoptilolite were prepared, variation of dielectric constant, dielectric loss, dielectric conductivity and relax session time were measured from 20Hz to 20KHz .Results were compared.
