スの悪影響等をさける事ができる。(f) Function Therefore, when using the conventional industrial hot press method, there is no need for complicated control of temperature, pressure, etc. up to the sintering of the ceramic powder material, which shortens the production time. Since the reduction in volume caused by sintering has already been completed, there is no need for correction for this, and since it is a sintered body, it is extremely easy to handle. In addition, uneven sintering that tends to occur when ceramic powder material is filled in a negative mold and fired can be avoided. In addition, if a fire-resistant investment material is used in the negative mold, the negative effects of the gas generated from it can be avoided.

特徴とする方法。Ceramic powder material is press-molded in order to separately manufacture a ceramic sintered body with a shape that almost matches the negative mold used in the industrial hot press method, which is a method of manufacturing ceramic products, and can be pressed. After molding using methods such as injection molding, extrusion molding, and tape molding, the ceramic sintered body is produced by firing.The separately manufactured ceramic sintered body is inspected for the presence of air bubbles and sintering defects. After this, the ceramic sintered body is softened at high temperatures and press-formed to finish the ceramic product into a precise shape.
