RESS and PCA are two complementary processes to produce particles in the submicronic range. In the RESS process it was found that coagulation processes have a stronger influence on the particle size than supersaturation. Droplet formation, as well as the precipitation in the droplets influences the particle size in the PCA process. Which of the two mechanisms dominates depends on the process parameters and material properties.
