Abstract

This work aims to investigate the effects of CuO doping (0–1.0 wt%) on the local structure of (Ba0.85Ca0.15)(Ti0.90Zr0.10)O3 (BCTZ) ceramics. These samples were prepared via the solid state combustion technique using glycine as fuel. The local structure of the samples was characterized by XANES (X-Ray Absorption Near-edge Structure) spectroscopy. The Cu, Ti K-edge and Ba L3-edge XANES measurements were performed in a fluorescent mode at ambient temperature. The XANES data revealed that the oxidation state of Ba and Ti ions in all samples was +2 and +4, respectively. Comparing the experimental Cu K-edge XANES spectra to theoretical XANES spectra simulated by FEFF program suggested that the substitution of the Cu ions for B-site ions in BCTZ lattice.
