Is shown, that slow crystallization of the system is accompanied by partial reduction of lead oxides to a metal (Pb0) state. The same results were found in the samples of the same composition with addition of 30% mol of PbO. The evidence for stereo active 6s2 lone-pair is discussed.8 pages, 6 figuresMaterials Sciencetext
