Description
(54) СТЕКЛО(54) GLASS
Изобретение относитс к составам стекол, используемым в электровакуумном и электронном приборостроении, например, при изготавлении вакуумноплотных окон св зи электронных гариборов.The invention relates to glass compositions used in electrovacuum and electronic instrumentation, for example, in the manufacture of vacuum-tight communication windows of electronic garibors.
Известно стекло, включающее SiOa, В2Оз, АЬОз, ЫгО.Known glass, including SiOa, B2Oz, HOS, UHD.
Цель изобретени - устранить опалесценцию , уменьшить температуру разм гчени и улучшить электрические овойСТ1ва стекла.The purpose of the invention is to eliminate opalescence, reduce the softening temperature and improve the electrical properties of glass.
Достигаетс это тем, что стекло содержит указанные компоненты в следующем количестве , вес. %: SiOz 68-71; 6263 25,5-27,5; 0,8-2,5; 0,2-1,5 и, кроме того, NaaO 0,2-2,6.This is achieved by the fact that the glass contains these components in the following quantity, weight. %: SiOz 68-71; 6263 25.5-27.5; 0.8-2.5; 0.2-1.5 and, in addition, NaaO 0.2-2.6.
Изобретение по сн етс конкретными составами и их свойствами, триведенными в таблице . 3 Стекло вар т в иварцевых и шамотных тигл х , в горшках или в ванных оечах три 1500-1600°С. . . .. Предметизобретени g Стекло, включающее SiOa, В2Оз, АЬОз, LiO2, отличаюш.еес , тем, , с целью 4 устранени опалесценции, уменьшени температуры разм тчени и улучшени электрических овойств, оно содержит указанные комно«енты IB следующем количестве, вес. %: SiO2 68-71; 25,5-27,5; АЬОз 0,8-2,5; Li2O 0,2-1,5 и, кроме того, Na2O 0,2-2,5. The invention is illustrated by specific formulations and their properties as described in the table. 3 Glass var t in ivartsevyh and fireclay crucibles, in pots or in bath bottles three 1500-1600 ° C. . . .. Subject of the invention g Glass, including SiOa, B2O3, ALOZ, LiO2, is distinguished by the fact that, in order to 4 eliminate opalescence, decrease the expansion temperature and improve the electricity supply, it contains the following rooms IB in the following quantity, weight. %: SiO2 68-71; 25.5-27.5; HOS = 0.8-2.5; Li2O 0.2-1.5 and, in addition, Na2O 0.2-2.5.
