Alkalifreies Aluminoborosilicatglas und Verwendungen

摘要

The invention relates to an aluminoborosilicate glass devoid of alkali, which has the following composition (in wt. % relative to the oxide content): SiO2 > 58 - 70; B2O3 0.5 - < 9; Al2O3 10 - 25; MgO > 8 - 15; CaO 0 - < 10; SrO 0 - < 3; BaO 0 - < 2; with MgO + CaO + SrO + BaO > 8 - 18; ZnO 0 - < 2. Said glass is eminently suitable for use as substrate glass, both in display technology and in thin-film photovoltaic technology.
