Abstract

Lead-free ceramic system (1-x)NaNbO3-xBaTiO3 for x = 0, 0.25, 0.50, 0.75 and 1.0 were prepared by conventional
ceramic technique. The ac conductivity data were found to obey the power law and showed negative temperature
coefficient of resistance behaviour. The ac conductivity data were used to evaluate the activation energy of the
compounds. The correlated barrier hopping model was found to successfully explain the mechanism of charge
transport in this system.
