Analysis of Hollow Spray Dried Dispersion Particles with X-ray micro-CT

The aim of this work was to investigate the feasibility of submicronCT to enable improved characterization of the morphological nature of SDD materials. The manuscript also suggests possible approaches to utilize the measured data in order to better understand the range of particle properties present within a sample. It is hoped that an improved handle on the SDD particle properties will enable improved linking of particle properties with processing conditions and downstream behaviour, and consequently, enable improved modelling of spray drying processes.
