Accuracy in the measurement of physical characteristics of ceramic starting powders is a critical factor in the control and reproducibility of powder processing unit operations. An international interlaboratory comparison program on powders characterization has been in progress under the auspices of the International Energy Agency. In this paper, the results of powder characterization effort on five powders by 25 industrial, university and governmental laboratories are presented. Selected results of density, specific surface area, and particle size distribution are presented and discussed in terms of factors affecting these measurements. The reasons for the discrepancies in the data are outlined.
