摘要：

Sodium bismuth titanate (Na1/2Bi1/2)TiO3 is strongly ferroelectric below 200 °C and antiferroelectric between 200 and 320 °C. The electrical conductivity of this ceramic is studied by measuring impedance as a function of temperature (RT-575 °C) and frequency (100 Hz-1 MHz). The complex impedance, electric modulus formalism and dielectric loss analysis are used to analyze the data. DC conductivity has been studied. The activation energies have been evaluated from the data. The dielectric constant of the sample has been calculated from the impedance data. © 2002 Published by Elsevier Science B.V.
