Description

Изобретение относится к технологии силикатов, а именно к составам стекол, которые могут быть использованы для изготовления изделий светотехнического, декоративно-художественного назначений.The invention relates to the technology of silicates, namely, compositions of glasses that can be used for the manufacture of lighting products, decorative and artistic purposes.

Известно стекло, содержащее SiO2, K2O, CaO и другие компоненты /1/.Known glass containing SiO 2 , K 2 O, CaO and other components / 1 /.

Известно стекло, содержащее, мас.%: SiO2 60-75; Zi2O 0-2; Na2O 3-13; K2O 0-12; Zi2O+Na2O+K2O 10-15; MgO+CaO+SrO 5-12; TiO2 12-18; осветлитель 0-0,1% /2/. Показатель преломления такого стекла 1,59-1,605.Known glass containing, wt.%: SiO 2 60-75; Zi 2 O 0-2; Na 2 O 3-13; K 2 O 0-12; Zi 2 O + Na 2 O + K 2 O 10-15; MgO + CaO + SrO 5-12; TiO 2 12-18; clarifier 0-0.1% / 2 /. The refractive index of such a glass is 1.59-1.605.

Цель изобретения - повышение показателя преломления стекла.The purpose of the invention is to increase the refractive index of glass.

Цель достигается тем, что в состав стекла дополнительно вводят BaO и R2O3, где R - элемент из группы лантаноидов, при следующем соотношении компонентов, мас.%: SiO2 54-60; K2O 5-6,5; CaO 10-12; TiO2 14-18; BaO 8-10; R2O3 5-1,5.The goal is achieved by the fact that BaO and R 2 O 3 are added to the glass composition, where R is an element from the group of lanthanides, in the following ratio of components, wt.%: SiO 2 54-60; K 2 O 5-6.5; CaO 10-12; TiO 2 14-18; BaO 8-10; R 2 O 3 5-1.5.

В таблице приведены составы стекла.The table shows the compositions of glass.
