X-ray powder diffraction structural characterization of Pb1 − xBaxZr0.65Ti0.35O3 ceramic

The structure of Pb1 − xBaxZr0.65Ti0.35O3 (PBZT) ceramic materials with 0.00 ≤x≤ 0.40 was studied using synchrotron X‐ray powder diffraction data. According to the Rietveld refinements, the structure of PBZT ceramics with x = 0.00, 0.10 and 0.20 at room temperature was rhombohedral R3c. A phase tran...

Zusammenfassung:The structure of Pb1 − xBaxZr0.65Ti0.35O3 (PBZT) ceramic materials with 0.00 ≤x≤ 0.40 was studied using synchrotron X‐ray powder diffraction data. According to the Rietveld refinements, the structure of PBZT ceramics with x = 0.00, 0.10 and 0.20 at room temperature was rhombohedral R3c. A phase transition from rhombohedral to cubic was observed at 543 and 463 K for x = 0.10 and 0.20, respectively. The refinement for the compositions x = 0.30 and x = 0.40 showed a cubic structure from 10 to 450 K, in good agreement with the dielectric properties of these samples.
