Particle shape
Quick Reference. Particle shape is defined by the relative dimensions of the long, intermediate, and short axes of the particle. The ratio of intermediate to long diameter and the ratio of short to intermediate diameter is used to define four shape classes. These are: oblate (tabular or disc-shaped forms); prolate (rod-shaped); bladed; and ...
