When a metal member and a ceramic member are joined to one another, an aluminum nitride sintered compact is prepared. A liquid and a component which is mutually reactive with the liquid are applied onto the aluminum nitride sintered compact, and then a copper foil is laminated thereon. Subsequently, when the members are left to stand at room temperature, the liquid and the component mutually cause an exothermic reaction. The aluminum nitride sintered compact and the copper foil mutually diffuse, and they are tightly joined to one another. Accordingly, the members to be joined are not thermally affected, and a desired joining strength can be obtained by using simple equipment.
Pour assembler un élément de métal et un élément de céramique, on prépare un comprimé fritté de nitrure d'aluminium. On applique sur le comprimé fritté de nitrure d'aluminium un liquide et un composant qui est mutuellement réactif avec le liquide, puis on y lamine une feuille de cuivre. Par la suite, quand les éléments sont laissés à température ambiante, le liquide et le composant causent mutuellement une réaction exothermique. Le comprimé fritté de nitrure d'aluminium et la feuille de cuivre se diffusent l'un dans l'autre et ils sont intimement liés. Par conséquent, les éléments à assembler ne sont pas thermiquement affectés, et l'on peut obtenir la force d'assemblage souhaitée à l'aide d'un équipement simple.
