Lanthanum strontium cobalt ferrite (LSCF), also called lanthanum strontium cobaltite ferrite is a specific ceramic oxide derived from lanthanum cobaltite of the ferrite (magnet), ferrite group. It is a phase containing lanthanum(III) oxide, strontium oxide, cobalt oxide and iron oxide with the formula , where 0.1≤''x''≤0.4 and 0.2≤''y''≤0.8.
It is black in color and crystallizes in a distorted hexagonal perovskite structure.
LSCF undergoes phase transformations at various temperatures depending on the composition. This material is a mixed ionic electronic conductor with comparatively high electronic Electrical resistivity and conductivity, conductivity (200+ S/cm) and good Ionic conductivity (solid state), ionic conductivity (0.2 S/cm). It is typically non-stoichiometric and can be reduced further at high temperature in low oxygen partial pressures or in the presence of a reducing agent such as carbon.
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 (selective barrier), membrane material for separation of oxygen from air, for use in e.g. cleaner burning power plants.
