Abstract
A mold for pressure-cast-molding a ceramic article having a filter material made of an open-cell porous material. The open-cell porous material is prepared by stirring a mixture of a resin material, a microballoon, a curing agent and water to provide an emulsion slurry, casting the slurry in a water-impermeable mold and curing the slurry in the water-containing state. The portions occupied by the water during the preparation of the porous material mainly form open pores.
