Abstract:
A method for producing a ceramic honeycomb structural body, comprising the steps of: providing raw materials for forming a cordierite composition; preparing slurries of respective raw materials to obtain raw material slurries respectively; allowing the thus obtained raw materials slurries to pass through a sieve having a mesh of 45 &mgr;m or less; subjecting the raw material slurries, that are passed through the sieve, respectively to spray drying to prepare raw material powders; mixing the thus prepared raw material powders to obtain a mixture having a cordierite composition; adding a forming agent and water to the thus obtained mixture to obtain a batch for forming; and subjecting the thus obtained batch for forming to an extrusion molding to obtain a honeycomb structural body having a wall thickness of 50 &mgr;m or less.
