The crystallization takes place in two stages: in the beginning, nucleation center arise, and then nucleation center grow. There are two mechanisms for the nucleation of the nuclei: crystallization centers:
- Homogeneous (spontaneous, spontaneous without extraneous particles);
- Heterogeneous (not spontaneous, with the participation of foreign impurities at the ready interfaces.)
The growth of crystallization centers does not depend on the method of nucleation of crystallization centers and obeys general laws.
The homogeneous crystallization theory.Continue reading →
