The influence of various factors on the redox potential of potassium borosilicate glasses has been studied. It is shown that this potential is formed under the influence of a number of oppositely acting factors, and often one of them is dominant. Thus, raw materials play a major role in the formation of the redox potential of highly alkaline glasses. When predicting it, one should take into account the nature and coordination state of acidic oxides. Tab. 1, ill. 2, bibliography: 7 titles.
The glass formation, structure, and physicochemical properties of glasses of the PbO - ZnO - B 2 O 3 -TeO 2 system were studied. The dual role of lead ions in structure of glasses. It is shown that the coordination transition of boron ions correlates with the PbO concentration in the glass. The nonlinear dependence of the properties of glasses on their composition is due to structural rearrangements in the glass. Il. 4, bibliography: 10 titles.
