Abstract: Methods of firing ceramic honeycomb bodies are disclosed that include heating the ceramic honeycomb bodies and blocking furnace gases from flowing through the ceramic honeycomb body by placing an aluminum metal layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the ceramic honeycomb body. The aluminum metal layer oxidizes to form a porous Al2O3 layer after firing to a first temperature, and furnace gases flow through the ceramic honeycomb body.

Abstract: Methods of producing a ceramic article include heating the ceramic green body containing a quantity of one or more organic materials to extract only a fraction of the organic materials from the ceramic green body by exposing the ceramic green body to a process atmosphere which is heated to a hold temperature of from 225° C. to about 400° C. and has from 2% to 7% O2 by volume of the process atmosphere. The method further includes cooling the ceramic green body to a temperature of below 200° C., exposing the ceramic green body to a higher concentration of O2 than in the process atmosphere of the heating step, and firing the ceramic green body to form the ceramic article. Volatile extraction units for implementing the methods are also described.

Abstract: Methods of firing ceramic honeycomb bodies are disclosed that include placing refractory particles on and end face of the green ceramic honeycomb body, and heating the green ceramic honeycomb body to a temperature of at least 600° C. to form a fired ceramic honeycomb body. The refractory particles prevents sticking of honeycomb-to-honeycomb during firing. A layer of refractory particles can also be used to replace a green cookie.

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° 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: A method for firing a ceramic honeycomb body including heating a green ceramic honeycomb body from a first temperature to a second temperature at a first heating rate and at a first oxygen level. Then, the green ceramic honeycomb body is heated from the second temperature to a third temperature at a second heating rate and at a second oxygen level. In this firing schedule, the second heating rate is greater than the first heating rate, and the second oxygen level is greater than the first oxygen level. Further, oxygen is introduced into the kiln to increase an oxygen level of the kiln from the first oxygen level to the second oxygen level near a peak of organic volatile release.
