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.
Claims4
A method for directly bonding a nonoxide-type ceramic member selected from the group consisting of nitride ceramic member and carbide member to a copper member, comprising the steps of:
- oxidizing a surface of said ceramic member to form an oxide layer 20 .mu.m or less in thickness,
- bringing said copper member into contact with the oxide layer of said nonoxide-type ceramic member, and
- heating said copper member and said nonoxide-type ceramic member at a temperature of from 1065.degree. to 1083.degree. C. in an inert gas atmosphere to directly bond said copper member to said nonoxide-type ceramic member.
