Crystallization process improvement
WebThermal-based process window limitations were recommended for both dynamically and isothermally cooled processes. These process windows are based solely on the melt and crystallization kinetics of the polymer and must be validated mechanically. However, this methodology eliminates entirely the guess and check methods that were previously used. WebCrystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of a crystal lattice is called a unit cell, which can accept atoms or molecules to grow a … For organic crystallization systems, the value of the growth order (g) is typically … However, effective and evidence-based crystallization process development and … Liu et al.
