Abstract
Structural investigations on ABO3 type perovskite dielectricresonator (DR) compounds, namely (Ba0.29Sr0.71)(Zr_0.973Ti_0.027)O_3 [BSZT] and (Ba_0.29Sr_0.71)(Zr_0.951Ti_0.039Ta_0.01)O_3 [BSZTTa] were carried out using X-ray Rietveld method. The structures were found to be isostructural with SrZrO_3 and belong to the space group Pbnm. In both the structures, the tilt angles of the BO_6 octahedra were lower than that in SrZrO_3. The volume of the octahedron was comparable for all the three. When Ta was substituted in BSZT, dielectric resonator properties of the resulting product BSZTTa improved substantially.Keywords
