Abstract

Individual powder particles were repeatedly cross-sectioned and examined at known intervals, sufficiently close to allow the same spheres to be cross-cut more than once. Micrographs of selected particles were taken at each stage. Simple chord measurements taken from the micrographs and the measured spacing between the corresponding cross-sections allows the calculation of both the particle diameter and the coating thickness. The accuracy of the results depends critically on the accuracy of the spacing measurement. The paper describes a simple, practical, and precise method for this measurement, eliminating the necessity for precision alignment and dedicated tools.
