Crystallization metastable zone
WebThe width of the metastable zone is system dependent and generally increases as the solute molecules become more complex and flexible. For inorganic salts the metastable zone may be 1 to 2 °C, however in pharmaceutical systems it is typically 20 to 40 °C, and in some instances it can be much larger.
