Abstract
In this paper is discussed how Raman spectroscopy can be used to distinguish if the synthesized material using precursor oxides is a simple phase mixture, solid solution or composite. This information is crucial to define how will be the physical properties of the synthesized material. Here was used NixPb1-xTiO3 and (NiTiO3)(x) + (PbTiO3)(1-x) samples prepared by solid state reaction, with x ranging from 0.0 to 1.0. Raman peak positions and full widths at half maximum of some more prominent peaks were used as probes. The results of these analyzes is very interesting and is useful as a guide, mainly for PbTiO3-based materials, but not only for. (C) 2016 Elsevier B.V. All rights reserved. (AU)
