Popis: Polarizing processes in lead monoxide were investigated. Certain anomalies were discovered in the temperature dependence of the permittivity and tg fi in the high temperature region near the phase transition. At low temperatures, in addition to these anomalies, intrinsic unipolar pyrocurrents were noted. The crystallographic structure analysis of the PbO modifications was investigated. Some space symmetry groups referred to lead monoxide are characteristic of ferroelectrics semiconductors. As a result of the experimental data analysis, it can be assumed that there is the probability of the formation of a ferroelectric situation in lead monoxide.
