· Sr4 Ta4 N4 O8

Sr₄Ta₄N₄O₈ is an oxynitride ceramic compound combining strontium, tantalum, nitrogen, and oxygen into a mixed-anion lattice structure. This material belongs to the family of transition metal oxynitrides, which are primarily investigated in academic and exploratory research settings for their potential to bridge properties between traditional oxides and nitrides. Industrial adoption remains limited, but the material shows promise in photocatalysis, energy storage, and advanced ceramics applications where the combination of metal cations and mixed anionic frameworks can enable novel electronic and optical properties.
