Summary

This paper will follow a literature survey approach, along with reference to personal industrial experience, to evaluate the different methods of preparing ceramic powders for dry pressing. Dry granulation and spray drying of slip will have their following properties compared: grain size distribution, flow properties, fill density, tap density, sintering behavior, etc. An attempt will be made to compare costs, along with justifying the cost/quality ratio. Finally an ideal powder, for the dry pressing process will be described.
