Ca1 Fe4 O8
semiconductor· Ca1 Fe4 O8
Ca₁Fe₄O₈ is an iron-calcium oxide ceramic compound belonging to the mixed-valence oxide family, with a crystal structure related to magnetite and other spinel-derivative phases. This material is primarily of research interest for energy storage and catalytic applications, where its mixed iron oxidation states and oxygen-deficient structure offer potential advantages in electrochemical systems and thermal energy conversion. While not yet widely commercialized, compounds in this family are being investigated as alternatives to conventional iron oxides in thermochemical storage, oxygen-ion conductors, and heterogeneous catalysis due to their structural flexibility and redox cycling stability.
