Lanthanum cobaltite

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.[1][2]

It is also common of LaCoO3 to be utilized with either dopants or exhibit oxygen non-stoichometry where it may assume the structure La1−xA'xCo1−yB'yO3±𝛿 where 𝛿 is some small quantity [3] making this class of perovskites extremely versatile for catalysis, one such commonly utilized material is lanthanum strontium cobalt ferrite otherwise known as LSCF.
