Lanthanum cobaltite is a perovskite with chemical formula LaCoO<sub>3</sub>. As a solid, the structure LaCoO<sub>3</sub>, will exist as rhombohedral material at room temperature with ferroelastic properties; though at temperatures above ~900 ðC a phase transition to a cubic lattice occurs.
It is also common of LaCoO<sub>3</sub> to be utilized with either dopants or exhibit oxygen non-stoichometry where it may assume the structure La<sub>1âÂÂx</sub>A'<sub>x</sub>Co<sub>1âÂÂy</sub>B'<sub>y</sub>O<sub>3ñð¿</sub> where ð¿ is some small quantity making this class of perovskites extremely versatile for catalysis, one such commonly utilized material is lanthanum strontium cobalt ferrite otherwise known as LSCF.
