ABSTRACT:

Nanopowders of Ba0.8Sr0.2TiO3 (BST) and BaZr0.3Ti0.7O3 (BZT) are synthesized using hydroxide co-precipitation method. The nanoparticles are used to form composites z BST + (1-z) BZT for z = 0.4, 0.5 and 0.6 with 2 wt% Bi2O3 as a sintering aid. The powders of BST, BZT and composites are subjected to the investigations of XRD, complex impedance and dielectric properties. The results on variation of dielectric constant are promising and suggest usefulness of composites as a RF dielectric material, in the paraelectric region.
