等、ホットプレス法は装飾用セラミックス焼結体の製造
方法としては著しく不適であると言わざるを得ない。However, it is very difficult to sinter titanium nitride, zirconium nitride, etc. alone, and special equipment such as a hot press is required to produce a sintered body by sintering titanium nitride powder raw materials alone. However, it is difficult to obtain a dense sintered body even using such equipment. Furthermore, considering the maintenance of the hot press equipment and the lifespan of the carbon mold and other molding materials used, this method is extremely disadvantageous economically and is not practical. In addition, in the hot press method,
Carbon is impregnated into the sintered body from the carbon molds and other mold materials used, causing a dark "dullness" on the surface of the sintered body, making it difficult to obtain a sintered body with a beautiful golden color, and furthermore, it is difficult to obtain a sintered body with a beautiful golden color. It must be said that the hot pressing method is extremely unsuitable as a method for manufacturing decorative ceramic sintered bodies, as it is extremely difficult to manufacture products with complex shapes as required by the industry.

た。Therefore, in order to obtain a high-density sintered body, titanium nitride raw material powder and zirconium nitride raw material powder were mixed with Fe, Co, Cr, and N.
Sintering is carried out by adding a low melting point metal such as i. When this method is used, a dense sintered body can be obtained at a relatively low sintering temperature, but even after high-level polishing, a glossy surface remains, making it difficult to obtain a polished surface with sufficient gloss.
In addition, there is a problem in that the metal components present in the sintered body undergo corrosion and change in color due to seawater, sweat, acid rain, etc., and the color tone suitable for use as a decorative member is lost.
本発明の目的は充分な光沢を有する美麗な黄金色を呈し

After molding, the inventors discovered that a titanium nitride sintered body that was sufficiently dense and had a beautiful golden color could be obtained by sintering it without relying on the pot press method, leading to the completion of the present invention.

% by weight, preferably within the range of 3-7% by weight. If the amount added is less than 0.5% by weight, a sufficiently dense sintered body cannot be obtained, the hardness is low, and a polished surface with sufficient gloss cannot be obtained. Moreover, if the amount added exceeds 10% by weight, a dense sintered body with gloss can be obtained, but a bright golden color cannot be obtained and the hardness also becomes low, which is not preferable.
