Description

Изобретение относится к области технологии силикатов, в частности к составам стекла, которое может быть использовано, например, в производстве электровакуумных приборов.The invention relates to the field of technology of silicates, in particular to glass compositions, which can be used, for example, in the manufacture of vacuum devices.

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

Известно стекло, содержащее SiO2 40,0-55,0%; Al2O3 10,0-18,0%; B2O3 5,0-10,0%; MgO 1,0-4,0%; BaO 1,0-10,0%; CaO 1,0-5,0%; ZnO 1,0-8,0%; кроме того R2О 4,0-7,0, причем SiO2+B2O3≤60% [2]. Термостойкость такого отекла составляет 180°С.Known glass containing SiO 2 40,0-55,0%; Al 2 O 3 10.0-18.0%; B 2 O 3 5.0-10.0%; MgO 1.0-4.0%; BaO 1.0-10.0%; CaO 1.0-5.0%; ZnO 1.0-8.0%; in addition, R 2 About 4.0-7.0, and SiO 2 + B 2 O 3 ≤60% [2]. The heat resistance of this edema is 180 ° 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 TiO2, при следующем соотношении компонентов, мас %: SiO2 50,0-55,0; Al2O3 10,0-15,0; B2O3 5,0-10,0; MgO 2,0-4,0; BaO 2,0-4,0; ZnO 10,0-14,0; TiO2 8,0-10,0.The goal is achieved by the fact that TiO 2 is additionally introduced into the glass composition, in the following ratio of components, wt%: SiO 2 50.0-55.0; Al 2 O 3 10.0-15.0; B 2 O 3 5.0-10.0; MgO 2.0-4.0; BaO 2.0-4.0; ZnO 10.0-14.0; TiO 2 8.0-10.0.

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