· JVASP-46787· Li2Si2Ni2O7

Li2Si2Ni2O7 is a lithium-based ceramic compound containing silicon and nickel oxides, belonging to the family of mixed-metal oxides with potential electrochemical or thermal applications. This is primarily a research material studied for its structural and functional properties rather than an established commercial ceramic; it is investigated in contexts involving lithium-ion conductivity, catalysis, or high-temperature stability where the combination of lithium, nickel, and silicate phases may offer advantages over single-phase alternatives.
