Oxidation ceramic to metal braze seals for applications in high temperature electrochemical devices and method of making

A method of manufacturing metal-to-ceramic seals comprising the steps of:

• a) providing an alumina forming metal part,
• b) heating said alumina forming metal part at a temperature and for a time sufficient to form an aluminized surface of the alumina forming metal part,
• c) providing a ceramic part,
• d) providing a braze material in between said alumina forming metal part and said ceramic part, said braze material containing braze temperature modifying agents wherein said braze temperature modifying agents are selected from braze temperature raising agents selected from the group consisting of Pd, Pt, and combinations thereof, and braze temperature lowering agents selected from the group consisting of V2O5, MoO3, and combinations thereof and
• e) heating said alumina forming metal part, braze material, and ceramic part in an oxidizing atmosphere.
