· Ca4 Ni4 O12

Ca₄Ni₄O₁₂ is a mixed-metal oxide ceramic compound containing calcium and nickel in a 1:1 cationic ratio, belonging to the family of perovskite-related or layered oxide semiconductors. This material is primarily investigated in research contexts for energy storage and catalytic applications, where the combination of earth-abundant elements (calcium and nickel) and tunable electronic properties make it a candidate for electrodes, oxygen reduction catalysts, or photocatalytic devices. Its development reflects ongoing efforts to replace or reduce reliance on rare-earth dopants in functional ceramics for environmental and cost reasons.
