Prevention of Ostwald Ripening Crystal Growth

The driving force for Ostwald ripening is the difference in solubility between the small and large particles (the smaller particles have a higher solubility than their larger counterparts). The difference in chemical potential between different sized particles was given by Lord Kelvin [2] [Eq. (13.1)]. 

Equation (13.29) shows that, the larger the difference between and ti, the higher the rate of Ostwald ripening. 

Ostwald ripening can be quantitatively assessed from plots of the cube of the radius versus time t [14,15],
