Abstract

FIELD: glass industry.
SUBSTANCE: invention proposes glass of the following composition, wt.-%: SiO2, 60.0-65.0; CaO, 6.0-10.0; K2O, 3.0-4.0; CeO2, 0.5-1.5; B2O3, 10.5-11.5; CdO, 8.0-10.0, and BaO, 4.0-6.0. The refraction index of glass is 1.65 ± 0.05, value of the temperature coefficient of linear expansion (TCLE) is (55 ± 5)°C-1 x 107. Invention provides reducing the temperature coefficient of linear expansion and increasing the refraction index of glass. Invention is designated for making articles for illumination equipments for industrial and domestic using.
EFFECT: improved and valuable indices of glass.
