XRD patterns of PMNT/ZnO ceramics sintered at 1,150°C and XRD peak at 2θ ≈ 45°. The figure on the left showed XRD patterns of PMNT/xZnO ceramics, where x = 0, 0.05, 0.1, 0.5, and 1 wt.% of CuO measured from an angle range of 10° to 60°. The other on the right showed a detail observation at angle ≈45° which indicated the shifting of a peak with ZnO additions.
