Summary

The ability to consolidate powders uniformly to near net shape is the essence of ceramic processing. This article discusses how one can use soil mechanic concepts to begin to understand the underlying causes of particle packing density variations in green bodies. Soil mechanics concepts relevant to conventional ceramic processing include permeability, effective stress, and the Terzaghi consolidation equation. It will be shown by computer simulation that quite large particle packing variations can develop during a typical slip casting operation. Improved understanding of the underlying causes of nonuniformity in green bodies will in turn lead to a better understanding of ceramic processing, new processing methods, and maybe expert manufacturing systems.
