Polymorphism: Ability of a material to exist in more than one form or crystal structure

  • BaTiO3, TiO2, ZrO2 etc. exhibit polymorphism
  • Allotropism is exclusively used for chemical elements exhibiting more than one form or crystal structure.
  • C, Fe, Zn etc. exhibit allotropism

In this section, we discuss SnTiO3 polymorphs.
