Ionic conductivity in Bi 2Sn 2O 7 ceramics
Impedance spectroscopy measurements, in the temperature range from room temperature to 600 K, were performed in order to investigate the dielectric and ionic properties of Bi 2Sn 2O 7 ceramics. The results show that the conductivity in this pyrochlore is associated with the hopping of ions. An activation energy of 1.26 eV was observed and the dielectric constant exhibits a strong contribution from ionic conduction. © 2011 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
