Ba2NiO

Ba₂NiO is a barium nickel oxide ceramic compound belonging to the class of mixed-metal oxides, where barium and nickel cations are coordinated within an oxygen lattice. This is a research compound with limited commercial production; it is primarily of interest in materials science for investigating electrochemical properties, magnetic behavior, and catalytic potential within the barium-nickel oxide system. Ba₂NiO and related barium nickel oxides are explored for applications in energy storage, catalysis, and solid-state electronics, where mixed-valence transition-metal oxides often exhibit useful electrochemical or magnetic properties that differ from their single-component counterparts.
