A novel method for measurement of crystal growth rate

A new method for measurement of crystal growth rate is proposed, in an attempt to make the measuring of growth rate more convenient than the existing methods. In this newly proposed method, the point of nucleation under a constant cooling rate condition was measured as changing the amount of seeds. The growth kinetics parameters were then estimated using the experimental data to match the points of nucleation. Experiments were performed with potash alum in the water system and growth kinetic parameters were estimated. Compared with existing results, the proposed method showed tolerable discrepancy in the growth kinetic parameters. The proposed method can be an alternative technique for measurement of growth rate.

► A new method for measurement of crystal growth rate has been presented.
► The new method does not require special equipment unlike other existing methods.
► Advantages of the new method are less time consumption and robustness on morphology.
► Growth rate obtained from the proposed method was similar to one from the existing study.
