Properties of glasses in the system Y2O3-Al2O3-SiO2 containing sodium and zirconium oxides were investigated. The difference between the thermal expansion coefficients at temperatures above and below softening point, density, and chemical durability were measured relative to the Al2O3/Y2O3 molar ratio.
