Electrical Properties of BaTiO₃ Doped with Lanthana and Niobia

Abstract:

The electrical resistivity (r), the dielectric constant (e), and the dielectric loss (tan d) were accurately measured in the temperature range 60-200oC for the samples (BaTiO3-La2O3-Nb2O5) with (Nb2O5 = 0.1) wt% and La2O3 = 0.0, 0.1, 0.2, 0.3 and 0.4). It is found that the addition of La content cause increase in resistivity and decrease the dielectric constant.
