Surface characterization of PZN ceramics prepared by a columbite B-site precursor

Pyrochlore-type PZN ceramics have been obtained from a two-stage process with columbite B-site precursor. In order to determine the chemical composition of these samples, a combination between X-ray diffraction (XRD) and X-ray photoelectron spec-troscopy (XPS) techniques has been performed. XRD anal...
