The influence of various additives on the porization of liquid-glass compositions using new approaches for analyzing experimental data, making it possible to obtain a quantitative assessment of the influence of inorganic additives and salts, is determined. Application of the law of constancy of the volume phase composition of dispersed systems makes it possible to express mathematically the influence of technological parameters (temperature, time) and the form of the types of additives introduced on the porization processes in such compositions.

The possibility of using substandard materials in the form of granulated concentrates in glass technology is analyzed. It is established that using granulated concentrates in glass melting intensifies the chemical activity of batches at the stage of silicate and glass formation, which is due to the finely dispersed and defective structure of the material, close contact of the high-melting components with soda, and increased homogeneity of the batch.

It is demonstrated that the density of binary glasses upon variation of the molar content of the modifier in their compositions obeys a parabolic dependence, whose parameters can be used to estimate the extent and type of reactions between the components. The reaction parameters in glasses that are prone to liquation are lower by an order of magnitude and have the negative sign. [ABSTRACT FROM AUTHOR]

The leachability of sheet glass in time and across the ribbon width is investigated using different methods. It is demonstrated that the method for determining the thermal-emission capacity of the surface makes it possible to characterize the chemical resistance of glass. [ABSTRACT FROM AUTHOR]

Expressions for the interaction parameter as a function of macroscopic glass parameters are derived within the framework of a model taking into account the interaction between the structural elements in binary glasses. Analysis of published data established that the interaction index in alkali-silicate glasses within the temperature interval in which the temperature coefficients of expansions are constant does not depend on temperature.

The effect of the duration of treatment of the surface of soda-lime glass in potassium and lead nitrate melts at a temperature of 460°C on the chemical and mechanical strength is investigated. It is demonstrated that the formation of a crystalline lead-silicate coating in this treatment increases the alkali resistance threefold and the mechanical strength of glass twofold. Practical recommendations are issued. [ABSTRACT FROM AUTHOR]

Lithium-aluminosilicate glasses have been melted and the physicochemical properties of glasses and glass ceramics crystallizing in two stages on the basis of these glasses have been studied. The study results are discussed. [ABSTRACT FROM AUTHOR]

The structure of multicomponent sodium-borosilicate glasses is investigated using the IR spectroscopy method, and their physicochemical properties are identified. It is demonstrated that enamels for protecting pipes used in the oil sector can be obtained on the basis of these glasses. [ABSTRACT FROM AUTHOR]
