N2 - The grain boundary phase of a lead-based relaxor was identified by Raman scattering spectroscopy using standard specimens including PbO, PbO2, and Pb3O4, as well as standard specimens synthesized from the compositions of the grain boundary phase analyzed by a scanning transmission electron microscope. It was revealed that the grain boundary phase contains the PbO phase along with the main perovskite phase in addition to the pyrochlore phase. This result agrees well with the results of X-ray photoelectron spectroscopy studies and strongly supports a previously described degradation mechanism for insulation resistance under humid loading conditions: dissolution of PbO in the grain boundary phase into water is the trigger phenomenon leading to degradation.
