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

A crystallizing glass solder for high-temperature applications, which is free of PbO and contains, 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; 2 to 7.0, preferably 4.4 to 7.0%, of MgO; 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 2% to 15%. 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.
