Abstract
Microstructural variability in ceramic green bodies has been a continuing issue during ceramic processing as it can lead to unwanted pores and fractures developing in the microstructure. Moisture and binders within the granules are needed to create temporary adhesion and strength before the firing process. The moisture governs the mechanical properties of the binder and thus affects the compaction behavior of the granules and the microstructure of the green body. In this study, alumina was the system analyzed and will be processed through thermal spray drying. The plasticity of the spray dried granules on a compaction scale is used as a tool to determine the effects of binder and characteristics within the slurry prior to spray drying have on the compaction behavior of the granules. Image analysis of compacted samples will be conducted to understand and determine what affects the microstructural uniformity and green strength of the compacted ceramic.
