  • Method for producing conductive honeycomb structure and method for producing electrically heating support
    Patent number: 11872721
    Abstract: A method for producing a conductive honeycomb structure includes: a forming step of extruding a forming raw material to obtain a honeycomb formed body; a drying step of drying the honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the honeycomb dried body to obtain a honeycomb fired body. The forming step includes controlling a volume fraction of a portion that can form pores of the honeycomb formed body so that an absolute value of a difference in the volume fraction of the portion that can form the pores in predetermined regions of the honeycomb formed body relative to a previously set, predetermined porosity of the honeycomb fired body is within 0.5%. The predetermined porosity is a porosity preset for each of the predetermined regions of the honeycomb fired body.
