The Estimation of Packing Characteristics by Centrifugal Compaction of Ultrafine Particles [Translated]†
At present, there is no reliable method available for determining the compaction characteristics of ultrafine particles, the sizes of which ranges from several to one hundred nanometers. In this paper, the authors propose the centrifugal compaction method to evaluate the compaction characteristics of the ultrafine particles by applying the self-compressive stress by centrifugal force in a packed powder bed. With such a system, compressive strains can be determined with good reproducibility as a function of centrifugal force. The relationships between compressive strain and centrifugal force for ten kinds of ultrafine particles, such as Fe, Co, Al, SiO2, Al2O3 and TiO2 were found to be divided into two categories. One category can be written as a linear relationship between the logarithm of compressive strain and the logarithm of centrifugal force, while the other can be described by a linear relationship between compressive strain and the logarithm of the centrifugal force.† This report was originally printed in J. Soc. Powder Technology, Japan. 26(9), 632-637 (1989) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc. Powder Technology, Japan.
