Kinetics of crystallization of highly anisotropic particles

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