Abstract: A method for firing a green honeycomb ceramic body in a kiln may include heating the green honeycomb ceramic body in four stages. The first stage may include heating the green honeycomb ceramic body from room temperature to a first temperature that at a first heating rate that is greater than or equal to about 75 o C/hr. The second stage may include heating the green honeycomb ceramic body from the first temperature to a second temperature at a second heating rate that is less than or equal to the first heating rate. The third stage may include heating the green honeycomb ceramic body from the second temperature to a hold temperature at a third heating rate that is less than or equal to the first heating rate. The fourth stage may include holding the green honeycomb ceramic body at the hold temperature to remove residual carbon.

Abstract: Methods of firing a cordierite green body to form a fired cordierite body. The green body comprises cordierite-forming raw materials and organic material, the body having a core portion and a skin portion. The green body is pre-heated to a pre-heat temperature that is less than a thermal decomposition temperature of the organic material. The green body is maintained at the pre-heat temperature for a period of time sufficient to minimize a temperature differential between the core portion and the skin portion. The green body is heated to a low firing temperature in a firing atmosphere sufficient to reduce a content of the organic material and to substantially remove chemically bound water from hydrous alumina. The green body is heated to a high firing temperature in a firing atmosphere sufficient to reduce the content of the organic material prior to a substantial removal of chemically bound water from clay.
