The mechanisms that govern powder flowability are complex and create an ongoing challenge in predicting and controlling flow behavior. Laura Shaw, Freeman Technology, and Jack Saad and Kara Bailey, Micromeritics Instrument Corp. | Feb 04, 2021 Flowability is a defining characteristic of powder intermediates and products. In manufacturing, powders with sub-optimal flow p...
