Abstract

A metal-ceramic joined body is provided in which the surface roughness of the metal is low, and the joined body is unlikely to break. Provided is a metal-ceramic joined body including a metal mainly composed of titanium and a ceramic, in which, regarding the X-ray diffraction peak intensity of a surface portion of the metal excluding a joining region to the ceramic, at least one of I 110 and I 012 is larger than I 011 , where I 011 is the intensity of a peak attributable to a first plane of hexagonal α titanium, I 110 is the intensity of a peak attributable to a second plane of hexagonal α titanium, and I 012 is the intensity of a peak attributable to a third plane of hexagonal α titanium.

First claim

What is claimed is:

1. A metal-ceramic joined body comprising a metal mainly composed of titanium, and a ceramic,
wherein, regarding the X-ray diffraction peak intensity of a surface portion of the metal excluding a joining region to the ceramic, at least one of I 110 and I 012 is larger than I 011 , where I 011 is the intensity of a peak attributable to the (011) plane of hexagonal α titanium, I 110 is the intensity of a peak attributable to the (110) plane of hexagonal α titanium, and I 012 is the intensity of a peak attributable to the (012) plane of hexagonal α titanium.

2. The metal-ceramic joined body according to claim 1 , wherein both the I 110 and the I 012 are larger than the I 011 .

3. The metal-ceramic joined body according to claim 1 , wherein I 013 is larger than the I 011 , where I 013 is the intensity of a peak attributable to the (013) plane of hexagonal α titanium.

4. The metal-ceramic joined body according to any one of claim 1 , wherein, regarding the full width at half maximum of the X-ray diffraction peak of the metal, at least one of the full width at half maximum of the peak attributable to the (110) plane of hexagonal α titanium and the full width at half maximum of the peak attributable to the (012) plane of hexagonal α titanium is smaller than 0.2°.

5. The metal-ceramic joined body according to any one of claim 1 , wherein the metal and the ceramic are joined by a metal solder.

6. The metal-ceramic joined body according to claim 5 , wherein the metal solder is mainly composed of gold.
