Seeded isothermal growth experiments are performed in a differential scanning calorimeter (DSC) and growth kinetics are obtained from the desupersaturation curve. Experiments are performed at temperatures ranging from 0 to 200 degrees C and high pressures utilizing sealed DSC pans. The technique introduced in this paper is useful in estimating growth kinetics in a relatively short period of time and under conditions of high pressure and temperature or, when only small amounts of material are available. Results obtained employing this method are in reasonable agreement with those in the literature.
