Ca4 Ni2 Ir2 O12

Ca₄Ni₂Ir₂O₁₂ is a mixed-metal oxide ceramic compound containing calcium, nickel, and iridium in a defined stoichiometric ratio. This material falls within the family of complex transition-metal oxides and is primarily of research interest rather than established industrial production; such compounds are investigated for their potential electronic, magnetic, or catalytic properties arising from the interplay of multiple metal cations in the crystal structure. Potential applications span solid-state chemistry, photocatalysis, and electrochemistry, where the combination of 3d transition metals (Ni) with a precious 5d transition metal (Ir) may enable novel functionality for energy conversion or catalytic processes.
