Abstract
Tungsten substituted samples of composition Ba (Ti1 − x W x ) O3 + δ are synthesized by solid-state reaction method. The prepared samples are characterized for their structural and electrical properties. X-ray analysis confirms the formation of single-phase perovskite structure. The microstructural studies reveal that the average grain size increases with increase in wolframium content. An increase in remanent polarization with increasing concentration of W has been observed. The maximum observed value of remanent polarization (P r) is nearly 2.67 μC/cm2 in the sample with x = 0.30. The maximum d 33 value is found to be 112.8 pC/N in the sample with x = 0.15.
