See full text

A composition is for the manufacture of glass solders for high-temperature applications up to temperatures of approximately 1000° C., which composition, having no ZrO2, has SiO2 at a proportion in the range from 48 mol-% to 62 mol %, Al2O3 at a proportion in the range from 0.5 mol % to 6 mol %, B2O3 at a proportion in the range 4 mol % to 12 mol %, BaO at a proportion in the range 12 mol % to 30 mol %, and either CaO at a proportion in the range from 2.5 mol % to 15 mol %, or an R2O3 at a proportion in the range 0.5 mol % to 20 mol % where the R2O3 is selected from La2O3, Y2O3, Sc2O3, and from a further oxide of a chemical element from the series of lanthanoids, wherein the SiO2:BaO ratio is in the range from 1.9 to 4.
