Characterization of Particulate Aluminas and Use in Evaluating Sintering Characteristics and Theory of the Initial Stage.

摘要

This paper reports the use of the methods developed for complete morphological particulate characterization on a series of alumina powders with the scanning electron microscope (SEM). An attempt is made at correlating the appropriate particulate characteristics with a sintering study performed on the same alumina powders. In addition, the porosities of the sintered aluminas are characterized using the lineal analysis techniques developed for the SEM yielding pore size and pore distribution data. Models are also proposed for further understanding of initial stage sintering.
