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 La_1−xA'_xCo_1−yB'_yO_3±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.
