    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.

    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.

    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: According to certain aspects, a wrapped green body carrier for a green body includes side supports and moveable supports mounted to the side supports. Each of the moveable supports includes an inner end configured to move relative to the side supports. The green body carrier includes a flexible sheet attached to and suspended from each inner end of the moveable supports. The inner ends of the moveable supports are configured to move inward to wrap the flexible sheet around at least a portion of the green body (e.g., more than 180°). Accordingly, the wrapped green body carrier supports a large circumference of the green body and accommodates large deviations in shape and/or diameter. In certain embodiments, the flexible sheet includes radiation coupling material or radiation blocking material so that wrapping the flexible sheet around the green body improves uniformity during microwave drying.

    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.
