Once an embryo has exceeded the critical size n* and becomes a stable nucleus, the growth stage begins.
Particle growth occurs by long-range atomic diffusion, usually involving three main steps:
Diffusion through the parent phase
Across a phase boundary
Into the nucleus
The growth rate, Ġ is determined by the rate of diffusion and is dependent on the temperature T:
C is a constant, Q is the activation energy, K is Boltzmann's constant and T is the temperature.
This dependency means at higher temperatures, the growth rate will be larger. However at these higher temperatures, nucleation rate is much less, meaning few embryos become a stable nucleus, however the few that do have rapid growth.
