A novel series of Zr1-xZnxP2O7 (x = 0.00, 0.03, 0.06, 0.1) was prepared by a solid state reaction method. XRD patterns indicated that all the samples exhibited a single cubic phase structure except Zr0.9Zn0.1P2O7. The conduction behavior was investigated using various electrochemical methods including ac impedance spectroscopy, isotope effect, gas concentration cells etc. in the temperature range of 300-600 degrees C. The conductivities were affected by the doping levels, and increased in the order: sigma (x = 0.00)
