Description

Изобретение относится к технологии силикатов и касается составов стекла, которые могут быть использован, например, в микроэлектронике.The invention relates to the technology of silicates and relates to glass compositions that can be used, for example, in microelectronics.

Известно стекло, содержащее следующие компоненты, мас.%: SiO2 25,0-32,0; В2O3 11,5-15,0; Al2O3 1,0-9,0; PbO 46,0-48,0; ZrO2 1,5-2,5; ZnO 1,0-6,0; SnO2 1,0-2,0 [1]. КТР такого стекла составляет (48-50)×10-7°С-1.Known glass containing the following components, wt.%: SiO 2 25,0-32,0; In 2 O 3 11.5-15.0; Al 2 O 3 1.0-9.0; PbO 46.0-48.0; ZrO 2 1.5-2.5; ZnO 1.0-6.0; SnO 2 1.0-2.0 [1]. The KTP of such a glass is (48-50) × 10 -7 ° C -1 .

Задачей изобретения является снижение коэффициента термического расширения стекла.The objective of the invention is to reduce the coefficient of thermal expansion of glass.

Технический результат достигается тем, что стекло, включающее SiO2, В2O3, Al2O3, PbO, ZrO2, ZnO, SnO2, дополнительно содержит BeO при следующем соотношении компонентов, мас.%: SiO2 25,0-32,0; В2O3 11,5-15,0; Al2O3 20,0-24,0; PbO 19,0-22,5; ZrO2 5,0-6,0; ZnO 1,0-6,0; SnO2 1,0-2,0; BeO 3,5-5,0.The technical result is achieved in that the glass, including SiO 2 , B 2 O 3 , Al 2 O 3 , PbO, ZrO 2 , ZnO, SnO 2 , additionally contains BeO in the following ratio of components, wt.%: SiO 2 25,0- 32.0; In 2 O 3 11.5-15.0; Al 2 O 3 20.0-24.0; PbO 19.0-22.5; ZrO 2 5.0-6.0; ZnO 1.0-6.0; SnO 2 1.0-2.0; BeO 3.5-5.0.

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