Effect of Oxides of Various Metals on the Physicochemical Properties of Glass in the PbO–CdO–SiO₂–B₂O₃–Al₂O₃ System

Abstract—The physicochemical processes occurring in glasses of the PbO–CdO–SiO₂–B₂O₃–Al₂O₃ system after high-temperature contact with oxides of various metals—CuO, NiO, Al₂O₃, TiO₂, Nb₂O₅, and WO₃, as well as the electrical resistance of the obtained glasses—are studied by X-ray phase analysis, infrared spectroscopy, and electron paramagnetic resonance. It is established that these properties are determined by the acid-base and redox properties of the oxides and glasses, which directly depend on the content of the O^2– ion in each specific composition.
