Abstract

The invention relates to an alkali-free aluminoborosilicate glass having a coefficient of thermal expansion &agr;20/300 of between 2.8·10−6/K and 3.6·10−6/K, which has the following composition (in % by weight, based on oxide): silicon dioxide (SiO2)>58-65, boric oxide (B2O3)>6-11.5, aluminum oxide (Al2O3)>20-25, magnesium oxide (MgO) 4-<6.5, calcium oxide (CaO)>4.5-8, strontium oxide (SrO) 0-<4, barium oxide (BaO) 0.5-<5, with strontium oxide (SrO)+barium oxide (BaO)>3, zinc oxide (ZnO) 0-<2, and which is highly suitable for use as a substrate glass both in display technology and in thin-film photovoltaics.
