Lanthanum strontium cobalt ferrite
Lanthanum strontium cobalt ferrite, 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 oxide, strontium oxide, cobalt oxide and iron oxide.
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 conductivity and good ionic conductivity. 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 material for separation of oxygen from air, for use in e.g. cleaner burning power plants.
It is commercially available.
