Lanthanum strontium cobalt ferrite
Lanthanum strontium cobalt ferrite (LSCF), also called lanthanum strontium cobaltite ferrite is a ceramic material of the ferrite group. It is a phase containing lanthanum(III) oxide, strontium oxide, cobalt oxide and iron oxide (cobalt iron oxide).
It is black in color and crystallizes in a distorted hexagonal perovskite structure.[1] LSCF undergoes phase transformations at various temperatures depending on the composition. This material is a mixed ionic electronic conductor with comparatively high electronic conductivity (200+ S/cm) and good ionic conductivity (0.2 S/cm).[2] 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.[3]
LSCF is being investigated as a material for intermediate temperature solid oxide fuel cell cathodes and, potentially as a Direct carbon fuel cell anode.[4]
LSCF is also investigated as a membrane material for separation of oxygen from air, for use in e.g. cleaner burning power plants. [1]
It is commercially available.
