MANUFACTURING METHOD FOR CERAMIC POROUS BODY, CERAMIC POROUS BODY MANUFACTURED BY THE METHOD, AND STRUCTURAL BODY

摘要

PROBLEM TO BE SOLVED: To provide a ceramic porous body having high grade and stable density and pore diameter.;SOLUTION: A mold 9 is composed of a cylindrical molding vessel 10 for receiving slurry 7 containing air bubbles from an air bubble introducing vessel 8 at its center, a plurality of openable and closable gates 11 provided in a lower part of the outer periphery of the molding vessel 10 to discharge the slurry 7 containing air bubbles in the molding vessel 10 radially and simultaneously, a plurality of funnels 13 for receiving the slurry 7 containing air bubbles discharged from the gates 11, a shutter 14 opening and closing tips in lower parts of a plurality of funnels 13 simultaneously, and a plurality of substantially cylindrical molding cylinders 15 for letting the slurry 7 containing air bubbles stored in upper parts of the funnels 13 flow into them simultaneously by opening the shutter 14 so that the slurry 7 containing air bubbles is made to flow into a plurality of molding cylinders 15 on substantially the same conditions.;COPYRIGHT: (C)2009,JPO&INPIT
