Abstract
The invention relates to compositions for producing glass solders for high-temperature applications up to temperatures of approximately 1000 DEG C and to the use thereof. The composition according to the invention contains SiO2 having a fraction in the range of 48 mol% to 62 mol%, Al2O3 having a fraction in the range of 0.5 mol% to 6 mol%, B2O3 having a fraction in the range of 4 mol% to 12 mol%, BaO having a fraction in the range of 12 mol% to 30 mol%, and CaO having fraction in the range of 2.5 mol% to 15 mol%, or an R2O3 having a fraction in the range of 0.5 mol% to 20 mol%, wherein the R2O3 is selected from La2O3, Y2O3, Sc2O3, and an additional oxide of a chemical element from the lanthanide series. An SiO2 : BaO ratio in the range of 1.9 to 4 is adhered to, and no ZrO2 is contained.
