Abstract
In a series of previous reports the effect of silica impurity on aggregation state and on electrophoretic, pressing, filtering and sintering behavior on alumina powders has been studied. The results obtained showed that the silica surface impurity plays an important role in the ceramic processing of powders by (a) decreasing pH values of the isoelectric point (i. e. p.), which affects the aggregation state of the powder, and (b) decreasing the compactability and the activation energy for the initial stage of sintering.
