Composition and synthesis development of building glass on the basis of non-standard raw materials

Abstract

Colorless building glass on the basis of non-standard raw materials with the use of discolourers-cerium oxide and potassium nitrate-was synthesized. The regularities of the cerium oxide addition effect on the light transmittance of the glasses are shown when the proportion of Na 2 O is replaced by K 2 O. The results of ORP and iron oxide equilibrium investigation in glasses, improvement of light transmission by means of correction of ORP glass are presented. The physical and chemical properties of glasses are measured: thermal coefficient of linear expansion (TCLE), water resistance and crystallization ability of glasses. The recommended composition of a building glass on the basis of non-standard raw materials is presented. © Published under licence by IOP Publishing Ltd
