FIELD: chemistry.
SUBSTANCE: invention relates to the glass industry, primarily to production of glass fibre having special properties. The glass for producing glass fibre, containing SiO2, Na2O and/or K2O, ZrO2, CaO, MgO, TiO2, Fe2O3, Al2O3, SO3, is characterised by that it contains said components in the following ratio, wt %: SiO2 - 61.0-65.0; Na2O and/or K2O - 23.0-25.5; ZrO2 - 10.0-13.0; CaO - 0.01-0.03; MgO - 0.01-0.05; TiO2 - 0.01-0.1; Fe2O3 - 0.02-0.1; Al2O3 - 0.1-1.0; SO3 - 0.1-1.0.
EFFECT: high chemical resistance in acidic and alkaline media, high operating temperature of articles.
