IPC: B01D39/20
Filed: 1987-06-04
Abstract: PURPOSE:To obtain a filter wherein strength is remarkably increased by inserting a soft porous foamed material into a vessel having inner diameter nearly smaller than the outer diameter of the foamed material, impregnating ceramic slurry to the foamed material and calcining it. CONSTITUTION:A columnar soft porous foamed material is inserted into a heat resistant vessel having an accepting part of a conformable shape properly smaller than the outer shape of the formed material. Thereby the peripheral part of the foamed material is compressed and compressibility is made large according to the direction directed to the outside from the inside. This compressed foam is impregnated with ceramic slurry, dried and calcined to obtain a filter. In this filter, the skeleton pores become gradually minute according to the direction directed to the peripheral part from the inside. Therefore the need for a conventional reinforcing layer for improving strength of the filter is eliminated and the particulate filter hardly to be broken can be produced at low cost.
