Polymorphic transition is a reversible transition of a solid crystalline phase at a certain temperature and pressure to another phase of the same chemical composition with a different crystal structure. For examples, the transitions of quartz (SiO2) at 1 143 K to tridymite, and at 1 743 K to cristobalite.
