Effect of Ostwald Ripening on Initial Droplet Size

4 Effect of Ostwald Ripening on Initial Droplet Size 

The importance of Ostwald ripening in determining initial droplet size in submicron miniemulsions can be realized by examining the particle size dependence of the characteristic time, Tqr, for Ostwald ripening, viz  

Ostwald ripening also has an effect on the initial particle size distribution. As the steady state equilibrium is approached, the particle size distribution will begin to order into the time-independent distribution given by eqns. (9.3) and (9.4). Thus, an emulsion which was initially nearly monodisperse will broaden over time, while a broad distribution will actually narrow over time.
