Abstract
A method for the adhesion of oxide type ceramics and copper or a copper alloy is provided by this invention, which method comprises placing the oxide type ceramics and the copper or copper alloy in mutual contact, heating them in an oxidative atmosphere thereby effecting adhesion thereof, and rapidly cooling the resultant composite of adhesion. The adhesive strength of the composite of adhesion so produced is about 40% higher than the adhesive strength of a similar composite of adhesion obtained by the conventional method involving gradual cooling.
