Abstract
A method for preparing a alternating-flow heat exchanger is disclosed, in which a ceramic structure is provided having straight, open-ended passageways therethrough.

The ceramic materials is fired for a temperature and for a time sufficient to form a monolithic ceramic alternating-flow structure.
