が現状である。(Prior art and problems) Conventionally, slurry-like materials are formed by injecting a slurry-like material into a plaster mold, and removing the slurry solvent from the slurry-like material by percolating into the plaster mold by capillary action. A common method is to solidify the powder using a binder added to the material. However, in the conventional method using a plaster mold, the strength of the plaster mold is weak, so the slurry solvent can be forcibly removed from the slurry by applying pressure. There is a problem that the rate of material deposition and water absorption vary from mold to mold and is not constant, and molded products made with plaster molds have uneven density, deform greatly when dry, and have weak strength. Ta. In addition, the plaster mold needs to be dried before the next molding, and the mold life is shortened due to erosion by the slurry solvent of the slurry-like material. Therefore, attempts have been made to use a sintered metal mold instead of a plaster mold to remove the slurry solvent, but this method creates small irregularities on the surface of the molded product. However, there is a problem that the pores of the mold become clogged early, so it is currently not in practical use.

Next, when a mold release agent is applied to the surface of the permeable film (3) to form a mold release film (4), a lower mold (5) for molding the desired slurry material is formed as shown in FIG. can get. Next, a porous solid body (6) made of sintered metal similar to that described above is installed in the upper frame body (7), and then a permeable membrane is applied to the cavity surface (6a) of the porous solid body (6). (8) and at the same time apply a mold release agent to the surface of the permeable film (8) to form a mold release film (9), thereby producing an upper mold (10) (see FIG. 2).

The slurry ceramic is injected while controlling the pressure at a pressure of 0"7. The slurry-like ceramic is made of 995% pure aluminum oxide powder (AL-1608G manufactured by Showa Denko K.K.)
100 parts by weight of acrylic resin emulsion (
3 parts by weight of E518 (manufactured by Chukyo Yushi Co., Ltd.), 2 parts by weight of polyethylene glycol, and 1 part by weight of glycerin were added as binders, and 25 parts by weight of water and a deflocculant (
0.3 parts by weight of D305 (manufactured by Chukyo Yushi Co., Ltd.) was added thereto, and the mixture was thoroughly mixed and peptized in a ball mill. As a result, the slurry ceramic is moved at a uniform speed toward the entire surface of the cavity surfaces (6a) (1a), and at the same time, the slurry solvent of the slurry ceramic is transferred to the permeable membrane (8) by the so-called pervaporation phenomenon. (3) and vaporizes to reach the porous solid body (6) (1), and then the porous solid body (6

etc. to rise. Next, the solid ceramic surrounded by the release films (4) and (9) is taken out from the lower mold (5) (see Figure 4), dried to completely remove the slurry solvent, and then Fire. By this firing, the mold release films (4) and (9) are burned out and the desired ceramic sintered body is obtained. Although the above process was repeated many times to remove the slurry solvent from the slurry ceramic by suction, the pores of the porous planar structures (6) and (1) were not clogged.
