Abstract:
A joint between a solid ceramic component and at least one other solid component, said joint comprising: at least three metal oxides of M1-M2-M3 wherein M1 is selected from the group consisting of BaO, SrO, CaO, MgO, and combinations thereof and wherein M1 is present in an amount from about 20 mol % to about 55 mol % and MgO is less than 90 mol % of that group and SrO is less than 24 mol % of the total, M2 is Al2O3 and wherein M2 is present in an amount from 2 to 15 mol %, and M3 is SiO2 with at least some B2O3 and up to 50 mol % of B2O3 and wherein M3 is present in an amount from about 40 mol % to about 70 mol %, said joint substantially matching a coefficient of thermal expansion of said solid ceramic component and said at least one other solid component.
