Au₂S is a gold sulfide intermetallic compound that belongs to the class of precious metal chalcogenides. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, with applications driven by its unique combination of metallic and semiconducting properties. Au₂S and related gold sulfides are investigated for electronic and photonic devices, corrosion-resistant coatings, and catalytic applications where the gold content provides both chemical stability and functional activity.
