Abstract
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.
Claims10
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.
