Abstract
The most promising region of glass compositions for obtaining hollow glass microspheres was determined using literature analysis. The main physical and technical characteristics of glasses have been studied and the dependence of the glasses properties on composition has been established. The influence of rheological properties of glasses near liquidus temperature on the processes of separation of gases previously dissolved in glass was established. It was shown that the loss
of the glass mass upon reheating is much higher than the amount of sodium sulfate dissolved in the melt and may be due to incomplete decomposition during melting of carbonates (in particular, sodium carbonate) included in the charge composition, as well as volatilization of B2O3.
