Electrical Properties of BaTiO3 Doped with Lanthana and Niobia
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.
