Т а б л и ц а I05 00 Yarbreteyu refers to the obtaining of glass junctions with metals, which are used in electrical and radio-electronic devices; special processing of the surface of the metal as well as thin film coatings. It is known glass for soypivevi with metal CID containing, May,%: Si 02 28.4-36.0; PCO 25,, O; 1102 2, O 12.0; 2.5-5.5; 4.5-11.4; NoijO 10.0-14.0; Li20 2.5-3.5; 4020 0.3-1.0; 51g2 Oj 2.0-4, O. The disadvantage of this glass is the presence of lead oxide in the composition, which is reduced by soldering and drastically reduces the dielectric characteristics of the glass. The closest to the proposed by theoosic essence and the achieved result is C 21 glass containing May. %: SiO 23, O-25, O; O, 13.0-14.0; NOI20 17, O-19, O; lO, O; L-i20 2, O-4, O; 7.0-9.0; 3.5-4.5; Co O O ,, 7; 2 ° tO, 13.0; CofO 6.0-8.0. However, this glass is characterized by waxy chemical resistance to water (weight after boiling glass powder in water for 5 hours, 5.7–9.2%), low dielectric properties, and the presence of expensive and low-density oxides T1gane, cobalt and danthan The purpose of the invention is to improve chemical resistance, dielectric properties and the thermal expansion coefficient. This goal is achieved by the fact that glass, including Si 02, N "20, KgO, 1,2, CdO, additionally contains CoiO, SnO, C-andO in the following ratio of components, May. %: 5,023.0-24.0% 0z13.0-14.0, 0-18.0 10.0-12.0 2.5-3.0 16.6-17.0 3.0-4 , O 7, O-9.5 2.3-2.5 0.2-0.4 Glass is cooked in a furnace with fuel oil heating in one- and three-liter quartz crucibles at 1100 ° C. The mixture is composed of reagent grade H and HCH. To determine the thermal coefficient, the boom extensions are drunk in the form of pegs and in the form of measurement disks. dielectric characteristics.
