Abstract:
A joint between at least two solid oxide ceramic parts comprising: at least three metal oxides of MAOXâ€”MBOYâ€”SiO2 combined together wherein MA is selected from the group consisting of barium, strontium, calcium, and combinations thereof, and MBOY is selected from the group consisting of Al2O3, B2O3, P2O5, GaO, PbO and combinations thereof and contains over 5 mol % Al2O3 and provides a melting temperature of the MAOXâ€”MBOYSiO2 combination below the melting temperature of MAOXâ€”SiO2, said joint substantially matching a coefficient of thermal expansion of said at least two solid ceramic parts wherein said MAOX is present in an amount from about 20 mol % to about 50 mol %, said MBOY is present in an amount from over 5 mol % to about 15 mol %, and said SiO2 is present in an amount from about 45 mol % to about 70 mol %.
