ceramic

· JVASP-10953· MgNi2O4

MgNi2O4 is a mixed-metal oxide ceramic compound belonging to the spinel family, composed of magnesium and nickel cations in an oxide matrix. This material is primarily investigated in research contexts for catalytic applications, energy storage systems, and as a precursor in electrochemical devices, where its structural stability and transition-metal activity offer advantages over simpler oxides. The compound is notable in battery electrode development and heterogeneous catalysis research, where nickel-based spinels are valued for their redox activity and thermal robustness compared to single-component oxides.
