Document Type and Number:
WIPO Patent Application WO/1996/020037
Kind Code:
A1
Abstract:
This invention provides a functional material-containing ceramic filter and a method of manufacturing the same. This invention also provides a ceramic filter the average particle diameter of which is the smallest at the surface with which a liquid to be purified is brought into contact and gradually increases continuously inward, and which is manufactured at a low material cost. A functional material-containing ceramic filter. A porous ceramic filter wherein the average diameter of fine particles constituting the filter increases continuously from at least one surface thereof inward. A material compound which contains a functional material as necessary is molded into a ceramic filter. The molding is done with ultrasonic vibration or with ultrasonic vibration and compaction applied to at least one surface of the molded piece. In manufacturing this ceramic filter, the extrusion molding die is provided on at least a portion thereof with an ultrasonic vibrator or with an ultrasonic vibrator and a compaction means.
