A method of joining metal and ceramic parts, wherein an alumina forming metal part and a ceramic part are provided. A braze material in placed between the alumina forming metal part and the ceramic part, and the combination is then heated in an oxidizing atmosphere, preferably in air at a temperature of between 500° C. and 1300° C. The alumina forming metal parts are selected from the group consisting of high temperature stainless steels, such as Durafoil (alpha-4), Fecralloy, Alumina-coated 430 stainless steel and Crofer-22APU, and high temperature superalloys such as Haynes 214, Nicrofer 6025, and Ducraloy. The braze material is selected as a metal oxide-noble metal mixture, preferably Ag-CuO, Ag-V<SUB>2</SUB>O<SUB>5</SUB>, and Pt-Nb<SUB>2</SUB>O<SUB>5</SUB>, and more preferably between 30.65 to 100 mole % Ag in CuO. |
