For pure materials, this 
For pure materials, this process can be accomplished using the Bridgman and Czochralski techniques; the latter can accommodate volume expansion during this process. The kinetics of this process can be described using an exponential equation named for Avrami, and this process has been empirically observed to pass through multiple states of decreasing energy, known as Ostwald's step rule. When this process occurs in polymers, a maltese cross pattern can be visible in polarized light. During the initial step in this process, an (*) "embryo" must overcome a critical size determined by the Gibbs-Thomson effect. A theory predicting the rate of this process proposed by Burton, Cabrera, and Frank accounts for the small number of kink and step sites. That theory is based on the presence of screw dislocations and predicts that rate is proportional to the square of supersaturation for low supersaturations. For 10 points, name this process in which a solute or liquid transitions into an ordered solid.
