Fast firing method for high porosity ceramics

A method for firing a green honeycomb ceramic body, the method comprising:

• heating the green honeycomb ceramic body from room temperature to a first temperature of less than or equal to about 350° C., wherein heating the green honeycomb ceramic body from room temperature to the first temperature comprises a heating rate of greater than or equal to about 80° C./hr;
• heating the green honeycomb ceramic body from the first temperature to a second temperature of greater than or equal to about 800° C., wherein heating the green honeycomb ceramic body from the first temperature to the second temperature comprises a heating rate of greater than or equal to about 90° C./hr;
• and
• heating the green honeycomb ceramic body from the second temperature to a third temperature of greater than or equal to about 1000° C.,
• wherein the green honeycomb ceramic body has a diameter of from greater than or equal to about 4.0 inches to less than or equal to about 9.0 inches,
• wherein the green honeycomb ceramic body comprises a carbon-based pore former in a concentration of from greater than or equal to about 10% to less than or equal to about 48% by weight, and
• wherein the green honeycomb ceramic body comprises aluminum raw materials for forming an aluminum titanate ceramic body.
