· JVASP-19299· Mg3Ni2O7

Mg3Ni2O7 is a ternary oxide ceramic compound combining magnesium, nickel, and oxygen. This mixed-metal oxide belongs to the family of functional ceramics and is primarily of research and development interest rather than established industrial production. The material is investigated for potential applications in electrochemistry, catalysis, and energy storage systems where nickel-containing oxides offer catalytic activity or ionic conductivity, with particular interest in emerging technologies such as fuel cells, supercapacitors, and battery electrode materials.
