An analysis of a large number of experimental data of various authors on the electrical conductivity of alkali-silicate glasses with different contents of alkali oxide has been carried out. It was found that for non-liquid glasses, the dependence of the electrical conductivity on the alkali oxide content is best expressed through its dependence on the average distance between alkali cations. Tab. 1, ill. 2, bibliography: 8 titles.
The effect of electron flux and gamma radiation on glasses obtained on the basis of a synthetic glass batch has been investigated. The nature of the radiation color centers formed in glasses and their decay during thermal and photobleaching has been studied. Tab. 1, ill. 3, bibliography: 8 titles.
It is shown that the redox potential (ORP) of glass is formed depending on the nature of the gases released during heating of raw materials. The redox potential of glass significantly affects the valence state of iron and copper and the oxygen coordination number of Cu (II) ions. Tab. 1, ill. 1, bibliography: 9 titles.
The structure of glass quenched with phosphorus has been studied using the methods of positron annihilation, X-ray phase and electron microscopic analysis, depending on the thermal prehistory. Structural differences were found depending on the wall thickness of the product and the temperature regime of annealing. The method is proposed to be used for express analysis of the homogeneity and degree of annealing of opaque glasses. Tab. 1, ill. 4, bibliography: 4 titles.
A method for calculating characteristic temperatures, performance indices and physical and chemical properties of container glasses, based on the use of calculated exposure factors, has been developed. The calculation method can be used both in production and in educational and research practice. Tab. 3, ill. 1, bibliography: 7 titles.
The influence of the coordination groups of boron, aluminum and silicon on the acid-base properties and the peculiarities of changes in the redox state of copper in boron-containing melts has been investigated. An approximate assessment of the acid-base properties of industrial glasses synthesized in an alkali-aluminum boron-silicate system has been carried out. Tab. 5, ill. 3, bibliography: 12 titles.
The results of theoretical studies on the quantitative assessment of the viscosity of glasses are presented. A new criterion for assessing the dynamic coefficient of viscosity is proposed. Tab. 5, ill. 1, bibliography: 8 titles.
The features of the use of organic compounds in the technology of glass modification (aliphatic alcohols and ketones, organic acids and their salts, organosilicon compounds) are considered in comparison with inorganic ones. It is shown that as a result of glass surface treatment with organic compounds, it is possible to improve the mechanical, chemical, colorimetric, biochemical and other properties of the glass. Tab. 4, ill. 2, bibliography: 11 titles.
The process of surface charge formation in phosphate glasses is investigated depending on the polarization conditions. A relationship has been established between the chemical composition and the ability to form internal electric fields upon irradiation of glasses of the type 0.50P 2 O 5 - 0.45RO - 0.05R 2 sub > O 3 . Il. 2, bibliography: 7 titles.
A program for calculating the performance characteristics of container glasses has been developed. The accuracy of determining the calculated values ??comparable to the experimental one was achieved thanks to the chosen algorithm and the use of correction factors established on the basis of a solid data bank of compositions and properties of container glasses.
