METHOD FOR PRODUCING HONEYCOMB FILTER
The present invention provides a method for producing a honeycomb filter in which scattering of organic decomposed materials, carbon, silica, and the like is suppressed in the degreasing step and the firing step to suppress attachment of organic decomposed materials, carbon, silica, and the like to the furnace walls, and the honeycomb filter can be efficiently produced under stable conditions. The method for producing a honeycomb filter of the present invention includes a molded body raw material preparing step of mixing silicon carbide powder, organic additives at least including an organic binder, and a silica-based pore-forming agent to prepare a raw material composition as a molded body raw material; a molded body producing step of extruding the prepared molded body raw material into a honeycomb molded body; a degreasing step of degreasing the produced honeycomb molded body; and a firing step of firing the degreased honeycomb molded body, wherein at the end of the degreasing step, the degreased honeycomb molded body contains silica including the silica-based pore-forming agent and carbon, and in the firing step, the silica is allowed to react with the carbon to synthesis silicon carbide.
