Particle surface geometry is important in determining the rate of dissolution in aqueous systems. Simplified models of dissolution kinetics that incorporate critical aspects of surface geometry can be formulated using a small number of parameters. For any dissolution model a chi‐squared minimization technique can be used to determine solubilities, rate constants, and other model parameters from standard time versus concentration dissolution data. Using this technique to determine parameter values for each model, geometric models describe better than any previous model a wide variety of kinetic data for the dissolution of apatite.
