Modeling of Binder Removal by Diffusion from Ceramic Green Bodies
David G. Retzloff and Stephen J. Lombardo, University of Missouri

This presentation delves into the fabrication of ceramic components via powder processing and the removal of the binder that aids in the processing of the ceramic green body. It begins with an introduction to the components involved in the process, and continues with the governing equations used for one-dimensional binder removal, decomposition reaction rate, as well as the relationships between weight fraction, volume fraction, specific volumes V1 and V2, and concentration as pertinent to the binder removal process. The presentation presents a step-by-step guide for how to model this in COMSOL.
