PROCESS FOR PRODUCING UNION COMPOSED OF MEMBER OF SINTERED ALUMINUM NITRIDE AND HIGH-MELTING-POINT METAL MEMBER

摘要

A process for producing integrated bodies from an aluminum nitride sintered body and a high-melting point metal member includes a step (I) of forming an aluminum nitride porous layer on a planned joint surface of the aluminum nitride sintered body; and a step (II) of causing a mixture paste including aluminum nitride and a high-melting point metal to be present between the aluminum nitride porous layer and a planned joint surface of the high-melting point metal member while impregnating the porous layer with the mixture paste, and sintering the aluminum nitride and high-melting point metal in the mixture paste.
