  Despite being applied with success in many fields of materials science, Raman
spectroscopy is not yet determinant in the study of electroceramics. Recent
experimental and theoretical developments, however, should increase the
popularity of Raman spectroscopy in this class of materials. In this Review, we
outline the fields of application of Raman spectroscopy and microscopy in
various electroceramic systems, defining current key bottlenecks and explaining
promising recent developments. We focus our attention to recent experimental
developments, including coupling Raman spectroscopy with other methodologies,
and modelling approaches involving both the model-based data interpretation and
the ab initio calculation of realistic Raman spectra.
