Overall growth and dissolution rates of potash alum crystals have been measured over the size range 3 to 70 μm. The derived surface integration growth kinetics, which are found to be linear with respect to supersaturation and strongly size dependent, are evaluated in terms of the step model of crystal growth. The results emphasize the importance of independently measuring growth kinetics before secondary nucleation kinetics can be calculated from MSMPR experiments.
