Abstract
Abstract A laminated body comprising a ceramic member and a metal member, and a method of forming the laminated body are described. The laminated body is characterized in that the ceramic member contains in its surface portion a bonding agent and the metal member is directly bonded to the surface of the ceramic member. The method of forming the laminated body is characterized in that a bonding agent-containing layer is first formed in the surface of the ceramic member and then the bonding agent-containing layer is heated while being contacted with the metal member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
72 words
A method for directly bonding a ceramic member and a metal member, comprising the steps of forming, in at least a surface layer of said ceramic member, a layer containing a bonding agent in an amount sufficient to bond said ceramic member to said metal member, and heating said ceramic member and said metal member while said ceramic member is in contact with said metal member through the bonding agent containing layer.
Claim 2
Independent Claim
72 words
A method for directly bonding a ceramic member and a metal member, comprising the steps of forming, in at least a surface layer of said ceramic member, a layer containing a bonding agent in an amount sufficient to bond said ceramic member to said metal member, and heating said ceramic member and said metal member while said ceramic member is in contact with said metal member through the bonding agent containing layer.
Claim 3
Dependent Claim
36 words
A method according to claim 1, characterized in that the heating temperature is below the melting temperature of the metal of said metal member and above the eutectic temperature of said metal and said bonding agent.
Claim 4
Dependent Claim
34 words
A method according to claim 1, characterized in that the method of treatment for forming said layer containing said bonding agent in said surface layer of said ceramic member is an oxidation treatment process.
Claim 5
Dependent Claim
20 words
A method according to claim 1, characterized in that said step of heating is performed in an inert gas atmosphere.
Claim 6
Dependent Claim
50 words
A laminated body comprised of a ceramic member and a metal member, said ceramic member having, in a surface layer thereof, a layer containing a bonding agent in an amount sufficient to bond said ceramic member to said metal member and said metal member being directly bonded to said layer.
Claim 7
Dependent Claim
50 words
A laminated body comprised of a ceramic member and a metal member, said ceramic member having, in a surface layer thereof, a layer containing a bonding agent in an amount sufficient to bond said ceramic member to said metal member and said metal member being directly bonded to said layer.
Claim 8
Dependent Claim
18 words
