Document Type and Number:

Japanese Patent JP4243514

Kind Code:

B2

Abstract:

To provide a composite ceramic having excellent wear resistance in addition to high strengths and high toughness and a method for manufacturing the same.

In the composite ceramic constituted of a zirconia crystal phase 1 containing 2.8-4.5 mol% Y2O3and a metallic phase 3 composed of one of Mo and W or a mixture of Mo with W, the average particle diameter of the zirconia crystal phase 1 is ≤0.35 μm, the average particle diameter of the metallic phase 3 is ≤1 μm, the content of the metallic phase 3 in the composite ceramic is 5-25 mass% and ≥95% of metallic phase 3 exists in the grain boundary of the zirconia crystal phase 1.
