An object of the present invention is to provide ceramics for decorative component, which has pinkish golden color tone and provides high-grade impression, aesthetic satisfaction and mind soothing effect, and has high mechanical properties such as hardness and toughness; and a decorative component using the same. The present invention relates to ceramics for decorative component, composed of titanium nitride-based sintered body, wherein the titanium nitride-based sintered body contains nickel, niobium, chromium and carbon, and wherein a content of carbon is not less than 1% by mass nor more than 2% by mass. According to the ceramics for decorative component of the present invention, since they are composed of a titanium nitride-based sintered body that contains nickel, niobium, chromium and carbon with its content of not less than 1% by mass nor more than 2% by mass, it is possible to provide ceramics for decorative component having pinkish golden color, that can enhance mechanical properties such as hardness and toughness and develops golden color with reddishness added thereto because carbon diffuses into titanium nitride to form a solid solution thereby accelerating sintering, and also can continuously provide high-grade impression, aesthetic satisfaction and mind soothing effect over a long period of time. |
