Abstract
Official abstract text for this publication.
An apparatus and method for debindering a cellular ceramic green body. The apparatus includes a flow modulation member to selectively restrict circulation of a heated oxygen-containing atmosphere through a top of a cellular core section of the green body. The method includes heating the green body in a circulating oxygen-containing atmosphere while selectively restricting circulation of the atmosphere through the top of the cellular core section of the green body.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for debindering a cellular ceramic green body comprising a top face and a bottom face with axial honeycomb channels extending therebetween, the method comprising: heating the green body in a circulating oxygen-containing atmosphere; and selectively restricting circulation of the circulating oxygen-containing atmosphere to the green body with a flow modulation sleeve around a side of the cellular ceramic green body; wherein the sleeve comprises a honeycomb body having a cavity into which the cellular ceramic green body can be placed. 2. The method of claim 1 wherein the sleeve surrounds an outer periphery of the cellular ceramic green body. 3. The method of claim 2 wherein the sleeve is spaced apart from the outer periphery of the cellular ceramic green body. 4. The method of claim 1 wherein the sleeve is comprised of cordierite. 5. The method of claim 1 , wherein the heating is performed while supporting the cellular ceramic green body on a horizontal support surface and wherein the sleeve blocks the circulating oxygen-containing atmosphere flow to an outer peripheral side of the cellular ceramic green body. 6. The method of claim 5 wherein the sleeve surrounds the outer peripheral side of the cellular ceramic green body. 7. The method of claim 6 wherein the sleeve is spaced apart from the outer peripheral side of the cellular ceramic green body. 8. The method of claim 5 wherein the sleeve is comprised of cordierite. 9. The method of claim 5 wherein the sleeve comprises organic material. 10. A method for debindering a cellular ceramic green body comprising a top face and a bottom face with axial honeycomb channels extending therebetween, the method comprising: heating the green body in a circulating oxygen-containing atmosphere; and selectively restricting circulation of the circulating oxygen-containing atmosphere to the green body with a flow modulation sleeve around a side of the cellular ceramic green body; wherein the sleeve comprises organic material.
