Glass formation with CaO, MgO and BaO in the system SiO2-B2O3-Na2O and their effect on some properties

Abstract

Тhe effect of alkaline earth oxides on the physicochemical properties of  easy-melting vitreous enamels for architectural and building products are  studied. It was established that with the increase of ionic radions of the elements of modifier introduced into the vitreous decreases the viscosity of the molten glass. Also, the dependence of surface tension on the vitreous content of alkaline earth oxides is increased while output modifiers limits up to 20%.
