Lanthanum cobaltite is a perovskite with chemical formula LaCoO3. As a solid, the structure LaCoO3, will exist as rhombohedral material at room temperature with ferroelastic properties; though at temperatures above ~900 °C a phase transition to a cubic lattice occurs.{{cite journal|last1=Kleveland|first1=Kjersti|title=Ferroeleastic Behavior of LaCoO3|journal=Journal of the American Ceramic Society|date=2001|volume=84|issue=9|pages=2029–2033|doi=10.1111/j.1151-2916.2001.tb00953.x }}{{Cite journal|last1=Petrov|first1=A.
