The Influence of Powder Surface Chemistry on The Development of Ceramic Microstructures (Sintering, Micro-Agglomerates, Adhesion)

The processing cycle of a ceramic is traditionally divided into two distinct steps: processing before and after firing. In terms of processing conditions and microstructure development, continuity is usually not assumed, and the variability of powder properties is usually thought to not affect the sintering activity of the powder. However, with the development of wet chemical methods of powder preparation, results have been reported in the literature which showed that processing conditions for active powders do indeed affect their subsequent behavior during firing. In particular, the influence of organic solvents on the behavior of fine ceramic powders has been reported for diverse systems such as alumina, zirconia, and PZT. The purpose of this investigation was to determine the role of powder surface chemistry during the development of ceramic microstructures.
