· Na12 Au4 O8

Na₁₂Au₄O₈ is an experimental mixed-valence oxide semiconductor combining sodium, gold, and oxygen in a layered or framework structure. This compound belongs to the family of ternary metal oxides and represents research-stage material chemistry rather than established commercial production. While not yet widely deployed industrially, gold-containing oxides in this compositional space are being investigated for potential applications in catalysis, solid-state ionics, and novel electronic devices where the unique electronic structure arising from gold's variable oxidation states could offer advantages over conventional semiconductors.
