Description

Изобретение относится к технологии силикатов, а именно к производству стекла, которое может быть использовано в строительстве, для изготовления изделий хозяйственно-бытового назначения.The invention relates to the technology of silicates, namely the production of glass, which can be used in construction, for the manufacture of household products.

Известны составы стекла, включающие SiO2, Al2O3, MgO, B2O3 и другие компоненты [1].Known glass compositions, including SiO 2 , Al 2 O 3 , MgO, B 2 O 3 and other components [1].

Известно стекло следующего состава, мас.%: SiO2 58,0-70,0; Al2O3 1,5-7,0; Fe2O3 0,08-0,5; CaO 2,0-9,0; MgO 0,6-5,0; Na2O 1,5-8,0; As2O3 0,08-0,5; кроме того, SiO2 0,5-3,0; K2O 2,0-12,0; SnO2 0,4-1,5; ZrO2 0,4-2,0; F' 0,505,0 [2]. КТР такого стекла составляет (76-88)×10-7°С-1.Known glass of the following composition, wt.%: SiO 2 58,0-70,0; Al 2 O 3 1.5-7.0; Fe 2 O 3 0.08-0.5; CaO 2.0-9.0; MgO 0.6-5.0; Na 2 O 1.5-8.0; As 2 O 3 0.08-0.5; in addition, SiO 2 0.5-3.0; K 2 O 2.0-12.0; SnO 2 0.4-1.5; ZrO 2 0.4-2.0; F '0.505.0 [2]. The KTP of such a glass is (76-88) × 10 -7 ° C -1 .

Целью изобретения является снижение КТР стекла.The aim of the invention is to reduce the CTE of the glass.

Цель достигается тем, что в состав стекла дополнительно вводят B2O3 и TiO2, при следующем соотношении компонентов, мас.%: SiO2 60,0-70,0; Al2O3 1,0-3,0; MgO 4,0-5,0; As2O3 0,1-0,3; SnO2 0,7-1,4; ZrO2 4,0-5,0; B2O3 15,0-20,0; TiO2 5,0-5,5.The goal is achieved by the fact that B 2 O 3 and TiO 2 are additionally introduced into the glass composition, in the following ratio of components, wt.%: SiO 2 60.0-70.0; Al 2 O 3 1.0-3.0; MgO 4.0-5.0; As 2 O 3 0.1-0.3; SnO 2 0.7-1.4; ZrO 2 4.0-5.0; B 2 O 3 15.0-20.0; TiO 2 5.0-5.5.

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