NaInO2N

NaInO₂N is an inorganic ceramic compound combining sodium, indium, oxygen, and nitrogen in a mixed-anion system. This material represents an emerging class of oxynitride ceramics being investigated for applications requiring thermal stability, ionic conductivity, or optical properties that bridge traditional oxides and nitrides. The compound remains largely in the research phase; it belongs to a family of inorganic semiconductors and ionically-conducting ceramics with potential relevance to energy conversion, sensing, and high-temperature applications where conventional oxides or nitrides show limitations.
