Abstract
The bonding of an external metal taken from the group of Cu, Ni, Fe, Ti, Mo and alloys thereof to an oxide ceramic substrate is accomplished through the use of an ionic diffusion accommodating metal oxide where the ionic diffusion oxide metal is taken from the group of Fe, Mn, Ti and the combination 33 Ni 67 V. The bond adhesion and processing parameters can be enhanced by addition of Li, Ni, Cu, Co and Mo and the ceramic can be at least one member of the group of glass, pyrex, Al.sub.2 O.sub.3 and SiO.sub.2 glass.
Claims12
In the attachment of an external metal to an oxide ceramic through the use of an intermediate metal oxide layer the improvement comprising imparting to the intermediate metal oxide layer the combined properties of formation of an oxygen-metal bond to said ceramic and an ionic difusion type bond with said external metal by providing in said intermediate metal oxide layer a metal from the group of Fe, Mn, Ti and the 33 Ni 67 V combination, providing as said oxide ceramic at least one member of the group of glasses, quartz, SiO.sub.2, Al.sub.2 O.sub.3 and combinations thereof and providing as said external metal at least one member of the group of Cu, Ni, Fe, Ti, Mo and alloys thereof.
A bond of an external metal taken from the group of Cu, Ni, Fe, Ti, Mo and alloys thereof joined to an oxide ceramic member having at least one ingredient taken from the group of glasses, quartz, Al.sub.2 O.sub.3 and SiO.sub.2 through an interstitial adhesion layer of an oxide of a metal taken from the group of Fe, Mn, Ti and the 33 Ni 67 V combination.
