Description
Изобретение относитс к составу стекол, используемому в электровакуумной и электротехнической промышленности дл спаивани заготовок с металлом, имеющих коэффициент термического расширени (90-100) 10- 1/град.The invention relates to a glass composition used in the electrovacuum and electrical industry for soldering metal blanks having a thermal expansion coefficient of (90-100) 10-1 / degree.
Известно стекло, включающее SiO2, ВоОз, СаО, ЫагО, К2О, МпгОз.Known glass, including SiO2, BOOZ, CaO, YAGO, K2O, MpGOz.
Цель изобретени - повышение химстойкости и снижение температуры разм гчени .The purpose of the invention is to increase the chemical resistance and decrease the softening temperature.
Достигаетс это тем, что оно содержит дополнительно ZnO, Li2O, TiOg и р2 при следующем соотнощении компонентов, вес.%: SiOa35-45This is achieved by the fact that it additionally contains ZnO, Li2O, TiOg and p2 with the following ratio of components, wt.%: SiOa35-45

Изобретение -по сн етс следующим конкретным примером (.вес.%): SiOj 35,60,- BjOs 13,3, ZnO 13,5,СаО 9,15, К2О 4,08, Na2O 7,22, LizO 2,65, TiO б;б5, Мп2Оз 2,85 .и HS -5,0. Этот состав вар т при температуре- -.1000°С, гранулируют и измельчают гр анул т. Предложенное стекло имеет коэффициент термического расщирени 95-10 1/град, химстойкость 1 гидрол 1тический класс, температуру разм гчени 460°С. С помощью предложенного стекла был получен спай керамического кольца с пластиной из железоликелевого сплава. Полученный спай обладал высокими термомеханическими свойствами и вакуумной плотностью.The invention is explained by the following specific example (.wt.%): SiOj 35.60, - BjOs 13.3, ZnO 13.5, CaO 9.15, K2O 4.08, Na2O 7.22, LizO 2.65 , TiO b; b5; Mn2Oz 2.85. And HS -5.0. This composition is boiled at a temperature of –1000 ° C, granulated and crushed. Annealed glass. The proposed glass has a coefficient of thermal expansion of 95–10 1 / degree, chemical resistance 1 hydrolytic class, softening temperature 460 ° C. Using the proposed glass, a junction of a ceramic ring with a nickel-iron alloy plate was obtained. The resulting junction had high thermomechanical properties and vacuum density.
