· JVASP-5806· PAuS4

PAuS4 is a gold-based intermetallic compound combining palladium, gold, and sulfur in a defined stoichiometric ratio. This material belongs to the family of precious metal sulfides and intermetallics, which are primarily of research and specialized industrial interest rather than commodity use. Applications are concentrated in high-reliability electronics, catalysis, and corrosion-resistant coatings where the combination of gold's noble-metal properties with enhanced hardness and thermal stability justifies the material cost.
