Abstract
Members of the Ba2Zn1−xCdxTa2O9 (0 ≤ x ≤ 1) series have been synthesized by solid state reactions at 1473K. Powder x-ray diffraction studies show a cubic perovskite cell with a ~ 4.1Å which increases with increase in x. Electron diffraction studies show the presence of hexagonal ordered perovskite structure in addition to the cubic structure seen by x-rays, the x = 0.5 composition showing more ordered crystallites. These samples show high dielectric constants with a maximum (∈r = 30 at 1 kHz) for the x = 0.5 member. The dielectric loss increases with increase in x at all the frequencies under study.
