摘要： A porous ceramic body is prepared by dipping an organic foam having a three-dimensional network structure in a ceramic slurry to deposit a sufficient amount of the ceramic on the surface of the foam, moving an excess of the ceramic slurry contained in the foam to the intended peripheral region of the foam by exerting centrifugal force on the foam, thereby causing denser ceramic deposition in the peripheral region than in the other region of the foam, and then drying, solidifying, and baking to burn out and dissipate the foam and simultaneously sinter the ceramics.
