Abstract
Quantitative characterization and analyses in powders and powder processing are necessary fundamentals for quality control and assessment of the products and the processes. The present report has been focused onto powder characteristics and random packing as the successive processing. Powders can be quantitatively characterized by diagramming both the measured sizes and shapes of the particles. A stereometric model has been proposed for the general powder particle in consideration of the shape. The random packing of spheres has been simulated for the given size distributions. The structures of the packed beds and the densities have been summarized. The quantitative relation between the powder characteristics and the packing density has been discussed.
