dc.description.abstractOxides of the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were obtained by the solid state reaction route at 1573 K and were found to crystallize in the disordered (cubic) perovskite structure. In Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 the entire range (0 ≤ x ≤ 1) of solid solutions could be synthesized. The dielectric constant decreases with increase in frequency for all compositions in the range 40 Hz to 100 kHz (r varies from 16 to 22). The dielectric loss (D) shows a broad maximum for both Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9. The maxima is centered around 2 kHz in the former and near 10 kHz in the latter.en
