Claims11
A ceramic member comprising:
- a ceramic sintered body;
- and
- a metallic member that comprises a metal element and is formed to be in contact with the ceramic sintered body, wherein
- the ceramic sintered body has an affected layer with a thickness of 300 μm or less around the metallic member.
1 more element
A method for producing a ceramic member, comprising the steps of:
- forming a ceramic compact;
- forming a metallic member comprising a metal element such that the metallic member is in contact with the ceramic compact;
- and
- sintering the ceramic compact and the metallic member,
- wherein the ceramic compact has a relative density adjusted to 40% or more and a ceramic sintered body at 1600° C. in the sintering step has a relative density adjusted to 80% or more, and the sintering step comprises a step of retaining an atmosphere under a reduced pressure at a temperature in the range of from 1500 to 1700° C.
