Image analysis tools and statistical procedures have been developed to quantify particle shape. Three copper sulfate crystallization processes have been carried out and the effects of process operating parameters upon crystal morphology have been studied as well as the relationships between morphology and powder end use properties. Both aspects give the capability to master end‐use properties by the process parameters. It is also shown that size distribution without morphology is deficient to globally characterize a powder and to describe its behaviour.
