Soda ash from nepheline raw materials: starting product for glass industry

The physicochemical and technological properties of soda ash from nepheline raw materials of improved modification and its effect on the processes of charge preparation, silicate-glass formation, as well as the properties of the glass produced have been studied. It has been established that in terms of its physicochemical, technological properties and storage behavior, soda of improved modification belongs to the category of "heavy", is a promising alkali-containing material and can be recommended for successful use in the production of glass containers, high-quality tableware and sheet glass, including decorative float glass with special properties.
