WIPO Patent Application WO/2016/052461

Kind Code:

A1

Abstract:

Provided is a method for producing a honeycomb filter, said method making it possible to carry out degreasing and sintering in a short amount of time, creating no risk of damage to a honeycomb molded article, having low energy loss, and making it possible to produce a honeycomb filter efficiently and at low cost. This method for producing a honeycomb filter comprises: a molded article starting material preparation step in which a molded article starting material is prepared by mixing silicon carbide powder and a starting material composition that includes an organic additive including at least an organic binder; a molded article production step in which a honeycomb molded article is produced by extrusion molding the prepared molded article starting material; a degreasing step in which the produced honeycomb molded article is degreased in a perfect inert gas atmosphere; and a sintering step in which the degreased honeycomb molded article is sintered in a perfect inert gas atmosphere.
