'''Polyamorphic systems''' and liquid-liquid transitions. Some solid compounds can exist in two or more ''polymorphs'' with different atomic structures but the same chemical composition.
*[[Germanium oxide]]
In the case of a pure element, this behavior is termed ''allotropy''.
*[[n-butanol]]
The existence of liquid polymorphs is known as ''polyamorphism'', i.e. the ability of a substance to exist in several different amorphous modifications.
*[[Phosphorous]]
Note: glasses are not in thermodynamic equilibrium, so such transformations do not correspond to true phase transitions from one stable liquid to another.
*[[Ramp model]]
