· JVASP-36448· Sr3N2

Strontium nitride (Sr₃N₂) is an ionic ceramic compound belonging to the family of metal nitrides, characterized by strong Sr–N bonding in an anti-bixbyite crystal structure. This material remains largely in the research and development phase, with investigation focused on its potential as a high-temperature structural ceramic, refractory, or functional material for advanced applications where thermal stability and chemical resistance are required. Sr₃N₂ is notable within metal nitride ceramics for its thermal properties and potential use in environments where conventional oxides may be limited, though industrial adoption remains limited compared to more established nitride ceramics like silicon nitride or aluminum nitride.
