New Guide Spotlights Analytical Techniques For Powders

Feb. 27, 2019
Micromeritics releases new white paper showcasing an optimal analytical tool kit for powders.

Micromeritics Instrument Corporation releases “The Definitive Guide to Powder Characterization,” a new whitepaper that showcases the analytical techniques available to optimally support the development and manufacture of commercially successful powder products. The paper explains how different techniques work and the value of the resulting data in building a comprehensive understanding of powder performance. Its applicability extends across the powder processing industries – from food and pharmaceuticals to additive manufacturing, catalysts and many more.

“Particles are usefully described as a small portion of matter, individual entities with, for example, a defined size and shape, while powders are more helpfully considered as bulk assemblies,” says Randy Byrne, Micromeritics global head of marketing. “They contain particles but also (most usually) air, and often moisture too. The properties of the particles that make up a powder product often define key aspects of performance – reactivity, sorption capacity, for example, or dissolution profile. They also, along with ‘system’ variables, such as the degree of aeration or consolidation, impact bulk powder properties such as the powder flowability. These, in turn, define both process and product performance.”

The paper covers techniques for analyzing particle structure, including surface area and porosity, for quantifying particle properties such as density, size and shape, and for the measurement of powder properties – flowability, compressibility, permeability and density. It also includes examples demonstrating how the techniques are applied together in specific applications, in the development of high-performance metal powders for additive manufacturing and robust formulations for oral solid dosage.
