Utilising the dynamic methodologies of the FT4, and good experimental design, it is possible to investigate a number of other behavioural properties of powders. These include: –
Caking
Powder consolidation with time
Moisture
The influence of free moisture on the behaviour of the powder
Segregation
The potential for particles to rearrange according to their size / density
Attrition
Particle friability, resulting in changes in particle size, shape and surface area
Electrostatics
Changes in behaviour as a function of electrostatic charging
Agglomeration
The formation of agglomerates from primary particles, usually as a function of being processed
