Powders are usefully thought of as bulk assemblies consisting of particles, (most usually) air and low levels of moisture. Particle properties often define critical aspects of product performance: the dissolution rate of a drug; catalytic activity; or the surface finish delivered by an abrasive.
However, particle properties also impact bulk powder behavior including flowability, compressibility, permeability and ease of fluidization. These properties, in turn, correlate directly with product and process performance: the fluidization performance of a catalyst; tablet hardness; and the feasibility of recycling an additive manufacturing metal powder.
The knowledgeable manipulation of the form and functionality of particles and powders is essential for commercial success and relies on a sound understanding of all relevant properties. Powder behaviour cannot currently be securely predicted from particle properties. This is why the development of cost-efficient processes and products with competitive performance demands a powder characterization toolkit that extends from particle structure through to bulk powder properties.
