Изобретение относитс к припоечным стеклам, примен емым в электровакуумно промышленности и может быть использовано дл герметизации приборов в вакуум при температуре 400-650 С.The invention relates to solder panes used in the electrovacuum industry and can be used for sealing devices in vacuum at a temperature of 400-650 C.
Известны составы припоечных стекол, содержащие Si 0 , , Со О , а также и 2, л О и некоторые другие компоненты 1 .The compositions of solder glasses containing Si 0,, Co O, as well as 2, l O, and some other components 1 are known.
Наиболее близким к изобретению вл етс припоечкое стекло, содержащее, вес. %: SiO 66-68; 2-3;Closest to the invention is a solder glass containing, by weight. %: SiO 66-68; 2-3;

Недостатком этого стекла вл етс то, что в его состав вход т летучие компоненты к InO , которые во врем герметизации в вакууме испар ютс и измен ют состав газовой атмосферы гфибора, что уменьшает срок его службы.The disadvantage of this glass is that it contains volatile components to InO, which evaporate during vacuum sealing and change the composition of the gas atmosphere of the digital fish, which reduces its service life.
Цель изобретени - повышение качества герметизации приборов в вакууме.The purpose of the invention is to improve the quality of sealing devices in a vacuum.
Это достигаетс тем, что стекло, включающее SiO,, и СаО, дополнительно содержит , и ВаО при следующем соотношении компонентов вес. %: SiOj 15-75This is achieved by the fact that glass, including SiO ,, and CaO, additionally contains, and BaO in the following ratio of components, weight. %: SiOj 15-75

Предлагаемое стекло изготавливают с лед тощкм обра зом.The proposed glass is made with ice and ice.
Шихту, состо щую из (Б вес. %); Si О, 56,8;Ае,Оз 2; Са О 3;3i.,O. 38,2 н Бел О 0s5 вар т в силитовой печи при температуре 1200 С, затем Е,ыливают ва стальную плиту. Полученное стекло размалывают, гфосеивают через сито 1590О DTB/CM , затем готов т суспен3i-Do порошка стекла, нанос т на корпус прибора и герметизируют его в вакууме.The mixture consisting of (B wt.%); Si O, 56.8; Ae, Oz 2; Ca O 3; 3i., O. 38.2 n White O 0 S5 is cooked in a silicon oven at 1200 ° C, then E, and a steel plate is poured. The resulting glass is ground, ground over a 1590 O DTB / CM screen, then slurry-i-do glass powder is prepared, applied to the body of the device and sealed in vacuum.
Стекло предлолюнного может быть применено дл герметизации приборо в вакууме без заметного испарени компонентов до температурь 700 С и показывает повышенный срок службы приборов и улучшенные характеристики сщокбы.Pre-molar glass can be used to seal the device in vacuum without noticeable evaporation of the components to a temperature of 700 ° C and shows an increased service life of the devices and improved characteristics of the scyba.
