PAuS4
metal· 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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
