The ceramic powder-processing process and the techniques to characterize powders, powder pressing and powder compacts are discussed. Powder pressibility and compaction response were found to be dependent on the properties and characteristics of a pressed powder. Powder characteristics, including particle size and surface area, were correlated inversely with pressibility. Powder compaction simulations can be used to predict density gradients, optimize pressing conditions and component geometry to minimize density gradients and evaluate powder pressibility. It was also found that the sintering behavior of a pressed powder was effected by the physical characteristics of the powder, particle/granule packing and pressed compact density.
