摘要：

Structural investigations on 4BO(3) type perovskite dielectric resonator (DR) compounds, namely (Ba0.29Sr0.71) (Zr0.973Ti0.027)O-3 [BSZT] and (Ba0.29Sr0.71)(Zr0.951Ti0.039Ta0.01)O-3 [BSZTTa] were carried out using X-ray Rietveld method. The structures were found to be isostructural with SrZrO3 and belong to the space group Pbnm. In both the structures, the tilt angles of the BO6 octahedra were lower than that in SrZrO3. 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.
