Abstract
A method for firing a green honeycomb body and for manufacturing a cordierite honeycomb body. The honeycomb body is heated from an initial kiln temperature to a first kiln temperature that is from about 300° C. to 400° C., at an oxygen concentration greater than 16%. The honeycomb body is heated to a second kiln temperature that is from about 600° C. to 700° C. at a second heating rate of greater than 125° C./hr. The honeycomb body is heated to a third kiln temperature that is from about 800° C. to 900° C. at a third heating rate that is less than or equal to the second heating rate. The honeycomb body is heated to a fourth kiln temperature that is from about 1300° C. to 1450° C. at a fourth heating rate that is less than or equal to the third heating rate.
