セラミックス部品の第二の特徴は、焼結体の表面が特定
の平均表面粗さを有する点である。The proportion of the sintering aid added to the ceramic is 2 to 20% by weight. This is for the following reason. If the mixing amount of the sintering aid is small, the action is not sufficient, it is difficult to mix uniformly, a good sintered body cannot be obtained, and if the mixing amount is large, the performance of the sintered body is deteriorated, which is not preferable. It is preferably 5 to 15%. The second feature of the decorative ceramic component of the present invention is that the surface of the sintered body has a specific average surface roughness.

What is the range of this average surface roughness? This is because it is possible to obtain a calm gloss that makes the best use of the black color of the sintered body, and when the roughness is less than this range, the gloss cannot be obtained. Preferably 0.01 μm
It is below. In order to secure the average surface roughness of the sintered body within the above range, the surface of the sintered body is mirror-finished by subjecting the sintered body to lapping, centrifugal barrel processing, or the like.

As a result, the surface color of the cufflinks of the example of the present invention was black, and the surface had a calm luster that makes the most of the black color. On the other hand, the cufflink of Comparative Example a was yellowish white, which is a typical color of aluminum nitride. The color of the cufflink of Comparative Example b was black,
The surface gloss was more stable than that of the inventive examples.
The color of the cufflink of Comparative Example c was also black, but it was not as black as that of the Example of the present invention.
