· K2 Au2 S4 O16

K2Au2S4O16 is a complex mixed-valence ceramic compound containing gold, sulfur, and oxygen in an ionic framework—a rare composition that sits at the intersection of sulfide and oxide chemistry. This material is primarily of research and academic interest rather than established industrial production; compounds of this type are studied for potential applications in solid-state ionics, catalysis, and advanced functional ceramics where unusual electronic or ionic transport properties might be exploited. Its notable characteristics stem from the presence of gold in a ceramic lattice, which is uncommon and may enable unique photochemical, redox, or electronic behaviors not available in conventional oxide or sulfide ceramics.

Regulatory Screening

Environmental

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.
