· JVASP-44231· Na2Ni2O3

Na2Ni2O3 is an inorganic ceramic oxide compound combining sodium, nickel, and oxygen in a layered crystal structure. While not a widely commercialized engineering material, this compound belongs to the family of mixed-metal oxides studied for electrochemical and catalytic applications, particularly in energy storage and conversion technologies. Its potential relevance lies in emerging research areas where nickel oxides are explored for battery cathodes, catalysts, and high-temperature ceramics, though practical engineering adoption remains limited compared to established alternatives like NiO or layered metal oxides.
