Electrical Properties and UV-Visual Spectra of (Na_0.535K_0.48) NbO₃ Ceramics Doped with Bi₂O₃ and Fe₂O₃

Abstract:

(Na0.535K0.48) NbO3 ceramics doped with Bi2O3•Fe2O3 are prepared by a ceramic process. The effect of Bi3+ and Fe3+ on microstructure and electrical properties of ceramics is investigated. X-ray diffraction shows that the structure of the material is perovskite. The conductivity of ceramics increases with the doping content. UV-Visual absorption spectrum is affected by doping Bi3+ and Fe3+. The mechanism of conductivity is discussed with respect to energy of band-gap in the system.
