Conductive Coatings, Sealing Materials and Devices Utilizing Such Materials and Method of Making

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

• a) providing a ferric non alumina forming stainless steel part selected from the group consisting of high temperature stainless steels and high temperature superalloys, said stainless steel part has greater than 23 mole % Cr,
• b) providing a ceramic part;
• c) providing a braze material in between said ferric non alumina forming stainless steel part and said ceramic part, said braze containing Ag and metal oxide wetting agents,
• d) heating said ferric non alumina forming stainless steel part forming part, braze material, and ceramic part in an oxidizing atmosphere.
