Wet vs Dry Processing: Granulation of Ceramic Powders (2nd in a Series)

Following the literature survey presented at the 1987 Division Meeting, this paper will evaluate different methods of preparing ceramic powders for dry pressing. Spray drying and several dry granulation techniques will be described and their powders characterized for flow properties, pressing behavior, and product characteristics. An attempt is made to compare the costs of preparing powders with these different techniques.
