Lanthanum strontium cobalt ferrite (LSCF), also called lanthanum strontium cobaltite ferrite is a specific ceramic oxide derived from lanthanum cobaltite of the ferrite group. It is a phase containing lanthanum(III) oxide, strontium oxide, cobalt oxide and iron oxide (cobalt iron oxide). LSCF is being investigated as a material for intermediate temperature solid oxide fuel cell cathodes and, potentially as a Direct carbon fuel cell anode. LSCF is also investigated as a membrane material for separation of oxygen from air, for use in e.g. cleaner burning power plants. It is commercially available.
