Fluxing effect of composite mineral material - cullet on the enamel glass

Synthesized enamel glasses based on the Na ₂ O - B ₂ O ₃ - Co ₂ O _{3 system} - SiO ₂ , including perlite, nepheline concentrate and broken glass. The physicochemical and technological properties of the obtained glasses and groundless coatings based on them have been studied. A comparative analysis of the fluxing effect of the compositions nepheline concentrate - glass breakage and perlite - glass breakage on glass is carried out. The areas of basic compositions suitable for the development of groundless powder glass enamels have been established. Tab. 2, ill. 2, bibliography: 4 titles.
