Application of lasers in the study of particle size and shape

Abstract

It's usually known that the particle size and particle shape are two irrelevant concepts. But our research shows that the token of particle size is not only related to particle shape, but also related to particle measurement methods. This paper takes sheetlike graphite micropowder for example and gets the function relation between particle shape factor and particle size by analyzing the particle distribution data between laser diffraction and sedimentation. This research provides a new approach for the study of particle shape.
