摘要： A method of slip casting using a casting mold provided with a water-absorbent layer that has a self-water-absorbent ability, substantially has a water resistance, and is controlled in the saturated water content thereof, the slip casting being conducted by employing mainly a capillary sucking force as the driving force of the water-absorbent layer of cast formation. An open-cell porous body usable as the water-absorbent layer is produced by agitating a mixture comprising a compound having at least one epoxy ring in its molecule, a curing agent which cures the epoxy compound by reaction, a filler developing for a self-water-absorbent ability and a mold release property, and water to prepare an O/W emulsion slurry and curing the slurry, as such in a hydrous state.

摘要： A porous, open-pore, hardened, plastic mold for shaping a ceramic article by any of various ceramic shaping methods. The mold is prepared by subjecting a water-in-oil emulsion to hardening in the desired mold shape without breaking the emulsion and then drying the hardened, shaped mold. The emulsion has incorporated in it any of sodium disilicate or disodium tetraborate to accelerate the shaping of the ceramic article in the mold. The emulsion may also have incorporated in it any of microbeads of glass, barite, quartz powder and powdered polymers to reduce the pure volume and increase the mechanical strength of the porous, open-pored hardened, plastic mold.

摘要： A method of forming a fine ceramics structure having columns with a fine pattern of width and a high aspect ratio includes steps of charging a plastic mold with a ceramics slurry, solidifying the ceramics slurry, and thereafter removing the plastic mold. The plastic mold is removed by heating the plastic mold in a vacuum, employing laser ablation, employing plasma etching, or employing a solvent of low viscosity dissolving plastic mold. Especially, the plastic mold is made of acrylic, the ceramics structure is made of lead zirconate titanate, and the mold is removed by plasma etching in a gas environment of oxygen and freon. The resulting fine pattern ceramics structure may have columns with an aspect ratio of at least 10, and particularly a height of 100 .mu.m and a diameter of 10 .mu.m.

摘要： In a casting method comprising casting a slip containing water or an organic solvent as the medium into a mold and removing the mold after solidification of the slip, use of a mold formed with an organic binder soluble in the medium of the slip allows the slip to quickly solidify and afford a green body due to absorption of the medium in the slip by the mold. In this case, the mold softens with loss of the binding power thereof simultaneously with the absorption of the medium. Therefore, no cracks appear at all in the green body, and removal of the mold is very easy.
