Expected particle size distributions of crystals produced from nonisothermal recrystallization.
It is shown, using oxalic acid dihydrate as a model, that nonisothermal recrystallization of powders gives rise to particle size distributions which approach log-normality in many cases. The number of particles formed is, primarily, a function of the nucleation rate constants and the particle size distribution, i.e., the mean diameter and standard deviation are functions of the growth kinetic parameters.
