Powder Characterisation: Chemical, Physical and Mechanical Properties

What will I learn?
This short course will outline the principles and methods for characterising the chemical, physical and mechanical properties of powders at length scales ranging from molecular level to single particles and to bulk levels. Sample preparation and the state-of-the-art techniques for particle characterisation will be detailed.

How will I benefit?
The course is delivered by over 10 presenters with internationally-leading expertise in their own speciality fields. The outcome of the course should enable you to choose what and how to characterise the powder and suspension properties, and to diagnose particular process and product issues of interest.
