Developing a Design Space for Powder Characterization

Powder characterization is not a single-parameter exercise, and frequently multiple metrics are required to provide useful insights into powder behaviour. However, large numbers of seemingly disparate parameters can be confusing and risk obscuring the useful data within. Here we discuss ways to amalgamate data from multiple test procedures in order to produce predictive models for the selection of candidate powders in manufacturing process. Whilst the method presented focuses on tablet manufacture for the pharmaceutical industry, this approach can be used across wide ranging industries in order to provide useful test methodologies and clear metrics for powder selection.
