Abstract

Disclosed is a dispersing agent which is used for a ceramic kneading composition that has small extrusion load and good moldability even when extrusion rate is increased. Specifically disclosed is a dispersing agent which is used in a ceramic kneading composition in a method for producing a ceramic product that comprises a process for extrusion molding the ceramic kneading composition. Also disclosed are a ceramic kneading composition, a method for extrusion molding a ceramic kneading composition, a ceramic product and a method for producing a ceramic product.
