Title:
CERAMIC STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/053679
Kind Code:
A1
Abstract:
This ceramic structure comprises a first layer that comprises first crystal particles, and a second layer that is positioned on the first layer and comprises second crystal particles. The first crystal particles and the second crystal particles each contain one or more metal elements that are selected from among Al, Si, Ti, Cr, Zr and Y, and one or more non-metallic elements that are selected from among N, C and B. The first crystal particles and the second crystal particles are composed of a same compound. If W1 is the half width of the peak of Miller index at the maximum intensity of the first crystal particles in the X-ray diffraction of the first layer, and W2 is the half width of a peak identical with the Miller index of the second crystal particles in the X-ray diffraction of the second layer, (9 × W1) > W2 > W1 is satisfied.
