Description

Изобретение относится к составам стекла, которое может быть использовано, например, для герметизации электроламп.The invention relates to glass compositions, which can be used, for example, for sealing light bulbs.

Известно стекло, содержащее SiO2, Al2O3, CaO, MgO, Fe2O3, ZnO, CuO и другие компоненты [1].Known glass containing SiO 2 , Al 2 O 3 , CaO, MgO, Fe 2 O 3 , ZnO, CuO and other components [1].

Известно стекло, содержащее, мас.%: SiO2 64,2-65,4; Al2O3 0,6-0,85; CaO 5,1-5,5; MgO 3,4-3,6; BaO 3,0-6,0; Na2O 11,5-11,9; K2O 4,6-6,0; Fe2O3 0,45-1,9; FeO 0,95-3,7; FeS 0,4-0,8 [2]. Термостойкость такого стекла составляет 135-146°С.Known glass containing, wt.%: SiO 2 64,2-65,4; Al 2 O 3 0.6-0.85; CaO 5.1-5.5; MgO 3.4-3.6; BaO 3.0-6.0; Na 2 O 11.5-11.9; K 2 O 4.6-6.0; Fe 2 O 3 0.45-1.9; FeO 0.95-3.7; FeS 0.4-0.8 [2]. The temperature resistance of such glass is 135-146 ° C.

Цель изобретения состоит в повышении термостойкости стекла.The purpose of the invention is to increase the heat resistance of glass.

Цель достигается тем, что в состав стекла дополнительно вводят ZnO и CuO, при следующем соотношении компонентов, мас.%: SiO2 64,0-66,0; Al2O3 0,5-1,0; CaO 4,0-5,0; MgO 3,0-4,0; BaO 2,0-2,5; K2O 3,0-4,0; Fe2O3+FeO 3,0-4,0; ZnO 10,0-12,0; CuO 5,5-6,5.The goal is achieved by the fact that ZnO and CuO are additionally introduced into the glass composition, in the following ratio of components, wt.%: SiO 2 64.0-66.0; Al 2 O 3 0.5-1.0; CaO 4.0-5.0; MgO 3.0-4.0; BaO 2.0-2.5; K 2 O 3.0-4.0; Fe 2 O 3 + FeO 3.0-4.0; ZnO 10.0-12.0; CuO 5.5-6.5.

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