Description

Изобретение относится к технологии силикатов, в частности стекла, предназначенного преимущественно для использования в электронной технике. The invention relates to the technology of silicates, in particular glass, intended primarily for use in electronic technology.

Известно легкоплавкое стекло, включающее V2O5, ZnO, B2O3, P2O5, ВаО.Fusible glass is known, including V 2 O 5 , ZnO, B 2 O 3 , P 2 O 5 , BaO.

Наиболее близким к предложенному стеклу по химическому составу является стекло, включающее следующие компоненты, мас. % : P2O5 17-23; V2O5 50-58; MoO3 7-9; TeO2 1-8; PbO 11-18. Такое стекло используется, например, для спаивания планшайб. Процесс спаивания производят при температуре 490-500оС.Closest to the proposed glass in chemical composition is glass, comprising the following components, wt. %: P 2 O 5 17-23; V 2 O 5 50-58; MoO 3 7-9; TeO 2 1-8; PbO 11-18. Such glass is used, for example, for soldering faceplates. The soldering process is carried out at a temperature of 490-500 about C.

Известные составы стекла обладают сравнительно высокой температурой спаивания (485-500оС).Known glass compositions have a relatively high soldering temperature (485-500 about C).

Целью изобретения является снижение температуры спаивания. The aim of the invention is to reduce the temperature of soldering.

Для этого в состав стекла дополнительно вводят SnO2, CdO, Al2O3, при этом содержание компонентов должно быть следующим, мас. % : V2O5 47-56; MoO3 5-7; P2O5 2-4; TeO2 1-4; PbO 11-18; SnO2 10-15; CdO 3-6; Al2O3 9-12.For this, SnO 2 , CdO, Al 2 O 3 are additionally introduced into the glass composition, while the content of the components should be as follows, wt. %: V 2 O 5 47-56; MoO 3 5-7; P 2 O 5 2-4; TeO 2 1-4; PbO 11-18; SnO 2 10-15; CdO 3-6; Al 2 O 3 9-12.

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

Температура спаивания описываемого стекла с металлами 480оС.The soldering temperature of the described glass with metals 480 about C.

Взвешенные в указанных количествах компоненты засыпают в корундовые тигли и загружают в силитовую электропечь. Варят стекло при температуре 950-1000оС в течение 0,5-1 ч. В остальном технология получения предложенного стекла не изменяется в сравнении с известной.Weighted in the indicated amounts, the components are poured into corundum crucibles and loaded into a silicon electric furnace. Cook glass at a temperature of 950-1000 ° C for 0.5-1 hours. The rest of the proposed technology for producing glass is not changed in comparison with the known.
