  • Publication number: 20210198153
    Abstract: Methods of firing ceramic-forming honeycomb bodies are disclosed that include heating the honeycomb bodies and blocking furnace gases from flowing through the honeycomb body by placing a layer selected from the group consisting of a graphite layer, a graphite-containing layer, an activated carbon layer, or an amorphous carbon layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the honeycomb body. The layer oxidizes to form a porous layer after firing to a first temperature, and furnace gases flow through the honeycomb body.
