FIELD: technology of silicates.
SUBSTANCE: invention relates to glass compositions that can be used in instrument making. Proposed glass comprises the following components, wt.-%: SiO2, 55.0-65.0; Al2O3, 2.0-4.0; B2O3, 13.0-17.0; P2O5, 3.0-7.0; CaO, 2.0-4.0; ZnO, 5.0-8.0; BaO, 2.0-3.0, and TiO2, 3.0-7.0. Invention provides decreasing coefficient of thermal expansion of glass.
EFFECT: improved and valuable property of glass.
