Kinetics Of Crystallization Of Highly Anisotropic Particles

An examination of the crystallization kinetics for the formation of anisotropic crystals are presented. In the case where crystallization results in the formation of spherical particles, then the transformation kinetics (i.e. the volume fraction crystallized as a function of time) is given by the standard Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation. However, when anisotropic crystals are formed, then the JMAK equation no longer suffices since their are certain particle interactions that cause a slowing down of the kinetics. Some of the theoretical modeling efforts that have been offered to address this situation are reviewed and some new presently ongoing work are described.
