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.

Webwithin the metastable zone and close to the solubility curve promotes crystal growth and helps to avoid secondary nucleation (Beckmann, 2000). In the case of in dustrial crystallizers as a general rule, the level of supersaturation is maintained at about half the metastable zone (Marciniak, 2002). 1.3 Nucleation and crystal growth WebThe metastable zone is bounded by the solubility curve and the metastable limit, which can be determined experimentally in an automated laboratory system [12,22]. The vast majority of pharmaceutical crystallization processes are designed so that the desired operation is within the metastable zone.
