In this study, the production of the porous ceramics usable for water purification filter is discussed. The porous ceramics were prepared by gelcasting method. Detergent and synthetic resin is mixed with slurry. After foaming the detergent, the slurry is solidified rapidly by the resin to keep the matrix structure. This method has already been applied to pure materials such as alumina with low curing shrinkage rate in precedence studies. In this study, the sediment had higher shrinkage rate that causes cracking in drying process, so that more amount of resin was added. The mixing ratio of water, sediment and detergent, and mixing time were changed for the discussion about the variation of characteristics of the porous ceramics.
Porosity and permeability could be increased by the higher water contents and longer mixing time while the strength was reduced at these conditions.
