Crystallization and matrix formation - Crystallization and the state diagram
3 important questions on Crystallization and matrix formation - Crystallization and the state diagram
What does the lever rule tell you?
How much of each crystalline phase will be present, the weight fraction of the ice.
Why do the glass transition and crystallisation areas overlap?
Because a material is typically glassy at low temperatures.
To get a crystal, you want to go slowly, as forming a crystal takes time.
To get a glass, you want to dehydrate quickly.

How are the glass transition and melting point related to the type of molecules?
Mobile molecules --> glass transition much lower than melting temperature
Rigid molecules --> difficult to rotate, glass transition temperature increases and becomes closer to the melting temperature
