Phase is the crystallization of the school to provide the driving force ,phase generated interface for nucleation of the crystal phase and provide a favorable nucleation bit ,make as nucleating agent composition enriched in two phases ,phase ,and then by it from the liquid phase to phase ,and crystal pulling out of l .
Nucleating agent to promote crystallization effect depending on the cation size and charge ,ugg italia (http://www.uggsaldi.net),high intensity of small cationic ,than the low field intensity cation more carefully to be orderly holding column oxygen ions surrounded so small cations are more prone to ordered crystal structure transition of L T field strength (I2=8.
