Title
(EN) Crystallizing glass solders and uses thereof
Abstract
(EN)

A crystallizing glass solder for high-temperature applications, containing, in % by weight on an oxide basis: 45% to 60% of BaO, 25% to 40% of SiO2, 5% to 15% of B2O3, 0 to <2% of Al2O3, and at least one alkaline earth metal oxide from the group consisting of MgO, CaO and SrO, wherein CaO is 0% to 5% and the sum of the alkaline earth metal oxides MgO, CaO and SrO is 0% to 20%, preferably 2% to 15%. The glass solder is preferably free from TeO2 and PbO. Preferred embodiments of the glass solder contain from 3 to 15 wt. % of Y2O3 and have low porosity and high stability with respect to a moist fuel gas environment.
