（産業上の利用分野）
本発明は、セラミックス製品の製造方法、特に球体状セ
ラミックス成形体の脱脂・焼方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a method for manufacturing ceramic products, particularly a method for degreasing and firing a spherical ceramic molded body.

で、球体加工を施して製造していた。(Prior Art) Conventionally, in order to manufacture ceramic spheres, a large number of spherical ceramic molded bodies are piled up in a container, placed in a heating furnace in this state to be degreased and fired, and then, It was manufactured using spherical processing.

低下させるという問題があった。(Problems to be Solved by the Invention) By the way, if degreasing and firing are performed on ceramic molded bodies in piles, the degreasing will be insufficient in the overlapping parts, and the molded bodies placed at the bottom of the container will not be degreased properly. There was a problem in that the weight from the molded body placed on one side caused a direction difference in shrinkage during firing, causing deformation and distortion, which reduced the efficiency during subsequent spherical processing.

とする。It was also considered to place these spherical ceramic molded bodies on each concave part of a plate with many concave parts and fire them, but in this case, the shape of the molded body also had a direction difference for shrinkage during firing. The present invention was developed in order to solve the problem of reducing the efficiency when machining spheres due to deformation and distortion. The purpose of the present invention is to provide a method for degreasing and firing a spherical ceramic molded body with high efficiency in spherical processing.

変形ヤ】歪が少なくなる。[Structure of the Invention] (Means for Solving the Problems) In the method for manufacturing a ceramic product of the present invention, when a spherical ceramic molded body is degreased and fired, the ceramic molded body has a radius of curvature larger than that of the spherical body. When the individual ceramic molded bodies are placed on the concave surface, separated, degreased, and fired,
The degreasing efficiency is improved, and the difference in direction of shrinkage during firing is reduced, resulting in less deformation and distortion.

で形成されている。As shown in Fig. 1, this degreasing/firing container 1 has a gas handling hole 2 on the side for degreasing, and as shown in Fig. 2, the inside has a radius of curvature larger than that of the spherical ceramic molded body. A setter 4 having a large number of concave surfaces is placed, and the containers can be stacked. Both the degreasing/firing container and the setter are made of ceramics such as silicon nitride.

形量が少なかったので加工能率が非常に良かった。In the present invention, a spherical lithium nitride ceramic molded body 5 is placed on the concave surface 3 of the setter 4, that is, as shown in FIG. It was placed on the formed concave surface 3, and the degreasing/firing container 1 was loaded and inserted into a heating furnace to perform degreasing and baking. Afterwards, we performed spherical processing, and the processing efficiency was very high because the amount of deformation was small.

体加工に非常に時間がかかった。On the other hand, in the conventional spherical ceramic molded bodies, which were degreased and fired in bulk in a container, the amount of deformation was large, and it took a very long time to process the spheres.

It also reduces deformation and distortion, making it possible to process spheres more efficiently.
