Methods for Analyzing the Experimental Data of Ostwald Ripining

The rate equation for describing Ostwald ripening and grain growth usually takes the form, Dn--D~ = kt (1) where D is the average grain size after annealing for time t, Do is the initial grain size, k is the rate constant and n a constant parameter. When Do is very small, the values of n and k can be readily obtained by assuming Do = 0. On the other hand, Do cannot be ignored when the initial grain size is large or rapid growth occurs during heating and cooling. Then the accurate values of n and k can be obtained only by fitting the data with Equation 1 using numerical methods as pointed out by Mistler and Coble.
