An Introduction to Particle Characterization

Introduction to Particle Characterization

Particle characterization involves analyzing size and shape to understand particulate behavior, including flowability, compaction, and mixing.

Size and shape greatly determine particle behavior, with spherical particles adequately characterized by size-only techniques. However, irregular particles require additional shape measurements.

Highly irregular shaped particles are challenging to characterize, but knowing only particle size is insufficient for raw material particles in manufacturing.

To understand particle behavior, measuring shape parameters and using tools that predict performance based on these parameters is necessary.

The irregularity of particles and their use in final products indicate the required shape measurements to optimize the final product.

No single metric is enough to fully characterize particles, especially irregular ones.

Author's summary: Particle characterization requires size and shape analysis.
