Abstract
A first member 10 containing at least ceramics and a second member 12 containing at least a metal or a metal composite was joined with each other. An adhesive 2 composed of a metal containing at least indium and materials 1A, 1B containing at least a component capable of reducing the melting point of indium between the first and second members to provide a laminate 13. The laminate 13 is heated at a temperature in solid-liquid coexisting range of an alloy comprising indium and said component to join the first member 10 and second member 12.
Claims18
A method of producing a joined body of a first member containing at least a ceramics and a second member containing at least a metal or a metal composite:
- the method comprising the steps of;
- providing an adhesive composed of a metal containing at least indium and a material containing at least a component capable of reducing the melting point of indium between said first and second members to provide a laminate;
- and
- heating said laminate at a temperature in solid-liquid coexisting range of an alloy comprising indium and said component to join said first and second members.
A joined body comprising a first member containing at least a ceramics, a second member containing at least a metal or a metal composite and a joining layer between said first and second members;
- wherein said joining layer comprises a phase of an alloy containing indium and a component capable of reducing the melting point of indium.
