Description

Изобретение относится к технологии силикатов и касается составов стекол, которые могут быть использованы для изготовления сортовой посуды, изделий декоративно-художественного назначения.The invention relates to the technology of silicates and relates to glass compositions, which can be used for the manufacture of high-quality tableware, decorative and artistic products.

Известно стекло, содержащее следующие компоненты, мас.%: SiO2 60,0-75,0; Li2O 0-2,0; Na2O 3,0-13,0; K2O 0-12,0; TiO2 12,0-18,0; осветлитель 0-0,1; Li2O+Na2O+K2O 10,0-15,0; MgO+CaO+SrO 5,0-12,0 [1].Known glass containing the following components, wt.%: SiO 2 60,0-75,0; Li 2 O 0-2.0; Na 2 O 3.0-13.0; K 2 O 0-12.0; TiO 2 12.0-18.0; clarifier 0-0.1; Li 2 O + Na 2 O + K 2 O 10.0-15.0; MgO + CaO + SrO 5.0-12.0 [1].

Задачей изобретения является повышение показателя преломления стекла.The objective of the invention is to increase the refractive index of glass.

Технический результат достигается тем, что стекло, включающее SiO2, K2O, CaO, SrO, TiO2, дополнительно содержит PbO, SeO2 и CeO2 при следующем соотношении компонентов, мас.%: SiO2 45,0-53,0; K2O 8,0-12,0; СаО 5,0-6,0; SrO 4,0-6,0; TiO2 14,7-17,8; PbO 11,0-14,5; SeO2 1,0-1,5; CeO2 0,1-0,3.The technical result is achieved in that the glass, including SiO 2 , K 2 O, CaO, SrO, TiO 2 , additionally contains PbO, SeO 2 and CeO 2 in the following ratio of components, wt.%: SiO 2 45.0-53.0 ; K 2 O 8.0-12.0; CaO 5.0-6.0; SrO 4.0-6.0; TiO 2 14.7-17.8; PbO 11.0-14.5; SeO 2 1.0-1.5; CeO 2 0.1-0.3.

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