EFFECT OF MODIFIERS ON RHEOLOGICAL AND THERMAL PROPERTIES OF BOROSILICATE GLASSES

Abstract

Results of research for the glass system Na2O-K2O-B2O3-SiO2 at 2:1 molar ratio of K2O/Na2O modifiers are presented. It has been found that increasing (K2O+Na2O)/B2O3 ratio in glass compositions leads to higher low-temperature viscosity and viscosity gradient in the range of 109-104Pa-s. The established temperature dependences of viscosity allow to optimize borosilicate glass compositions with predetermined characteristics, as well as technological parameters of their synthesis and formation.
