Document Type and Number:
WIPO Patent Application WO/2014/181827
Kind Code:
A1
Abstract:
Provided is a zirconia sintered body with improved strength between the layers of laminated powder. Multiple zirconia powders are formed having different compositions and containing zirconia and a stabilizer for suppressing phase shifts of the zirconia, a zirconia composition is formed by laminating the multiple zirconia powders, and a zirconia sintered body is produced by sintering the zirconia composition, the bending strength thereof being 1100MP or greater, measured in conformity with JISR 1601 on a sintered body test piece in which the boundaries of the multiple zirconia powders traverse the test piece along the load applying direction, the load points being aligned with the boundary positions in the three-point bending test.
