Abstract:
A method for joining characterized by comprising:the first step of forming, on a joint surface of a base made of a metallic oxide, a solution layer formed from a solution in which a compound containing a metal and oxygen of the metallic oxide is dissolved; the second step of heating the solution layer to form, on the joint surface of the base, an adhesion layer containing the metal and oxygen in an intermediate phase state which is unstabler than the metallic oxide and in which an energy level tends to change into a lower level; and the third step of arranging another member on the adhesion layer, and applying a pressure between the base and said another member while heating the adhesion layer to cause phase transition of the adhesion layer in the intermediate phase state to the metallic oxide with a stabler phase than that of the adhesion layer, thereby joining the base to said another member.
