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. In the case of a pure element, this behavior is termed allotropy. The existence of liquid polymorphs is known as polyamorphism, i.e. the ability of a substance to exist in several different amorphous modifications. Note: glasses are not in thermodynamic equilibrium, so such transformations do not correspond to true phase transitions from one stable liquid to another.
