COMPOSITION FOR PRODUCING GLASS SOLDERS FOR HIGH-TEMPERATURE APPLICATIONS AND USE THEREOF |
摘要 |
The invention relates to compositions for the manufacture of glass solders for high-temperature applications up to temperatures of approx. 1000° C. and to their use. SiO2 having a proportion in the range from 48 mol-% to 62 mol %, Al2O3 having a proportion in the range from 0.5 mol % to 6 mol %, B2O3 having a proportion in the range 4 mol % to 12 mol % and BaO having a proportion in the range 12 mol % to 30 mol % as well as CaO having a proportion in the range from 2.5 mol % to 15 mol %, or an R2O3 having a proportion in the range 0.5 mol % to 20 mol % are contained in the composition in accordance with the invention, where the R2O3 is selected from La2O3, Y2O3, Sc2O3 and from a further oxide of a chemical element from the series of lanthanoids. In this respect, an SiO2:BaO ratio in the range from 1.9 to 4 is observed and no ZrO2 is contained. |
