MANUFACTURE OF CERAMIC HONEYCOMB STRUCTURAL BODY

摘要

PROBLEM TO BE SOLVED: To obtain a high quality ceramic honeycomb structural body with a low heat capacity by a method wherein the cell wall is prevented from falling out at an extrusion molding when the thickness of the cell wall is made thinner. SOLUTION: After one or more kinds of ceramic stocks prepared so as to realize a desired ceramic composition is measured, before a kneading process is executed, the ceramic stocks forming agglutinated particles among the ceramic stocks are dispersed in advance in a solvent with either one or both of a chemical and a physical dispersing methods in order to realize the ceramics, which pass the slits of an extrusion mold. The resultant solution is added with other ceramic stock without drying so as to obtain a body, the re-agglutination of which is prevented from occurring, through kneading in order to allow to extrusion-mold under the state that stock particles are dispersed.
