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. 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). 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. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lanthanum strontium cobalt ferrite」の詳細全文を読む スポンサード リンク
