· JVASP-44482· Li4NbFe5O12

Li4NbFe5O12 is a lithium niobium iron oxide ceramic compound belonging to the garnet or spinel family of mixed-metal oxides. This is primarily a research material investigated for electrochemical and magnetic applications, rather than a mature commercial ceramic. The material's potential lies in energy storage (as a solid-state electrolyte candidate), magnetic device applications, or catalytic uses, where the combination of lithium, niobium, and iron oxides offers tunable ionic conductivity or magnetic properties depending on crystal structure and defect chemistry.
