Opacified glazes on the base of liquiating glass of low-alkali alloys

The processes of glass formation in the system Na ₂ O - MgO - CaO - B ₂ O ₃ - SiO ₂ , and also the influence of heat treatment modes on the location of segregation regions, the nature, structure and phase composition of the liquidating glasses and the kinetics of segregation processes. The physicochemical characteristics of glasses have been determined, which make it possible to confirm the presence of inversion of liquation phases. Compositions of liquidating glazes with a minimum content of damping zirconium-containing components have been developed. Il. 4, bibliography: 5 titles.
