KINETICS OF NUCLEATION AND GROWTH .1. REACTION CONTROLLED GROWTH

A number of solutions have been obtained to describe the size distributions and average particle size for nucleation and reaction controlled growth of precipitates; this includes the solutions for constant nucleation rate, the exponential nucleation law, Kashchiev's equation and some multistep nucleation models. The increase in the average particle size is related to increase in maximum size. Time-dependent effects occur if nucleation is affected by an induction time or a decay time.
