monotropic transition
The irreversible transition from a metastable polymorphic form to the stable polymorph. Example: The transition of metastable CaCO3 (aragonite-type) to the stable CaCO3 (calcite-type).
Note:
For liquid crystals the term refers to a liquid crystal to liquid-crystal transition that occurs below the melting point and is revealed by supercooling of the crystal.
