GLASS Russian patent published in 1994 - IPC

Abstract RU 2023691 C1

FIELD: glass. SUBSTANCE: glass has the following components, wt.-%: silicon oxide (SiO2) 25-45; aluminium oxide (Al2O3) 26-40; calcium oxide (CaO) 12-35; boron oxide (B2O3) 5-12; fluorine (F′) 2-10. Also, glass can contain cobalt oxide (Co2O3) 0.2-0.5 wt.-%. Glass properties: insulation resistance before testing is 1·1013-1·1014Оhм, after testing at 200 C for 1000 h, 7 thermocycles (-50)-(+200 C) resistance is 1·1012-5·1012 Ohm, breakdown voltage before and after testing is 600-680 and 570-63o v, respectively. Glass is used for making of thick-film interlayer insulation. EFFECT: enhanced quality of glass. 2 cl, 2 tbl
