· Na1 S2 Y1

Na₁S₂Y₁ is an experimental ternary compound combining sodium, sulfur, and yttrium in a semiconducting phase. This material represents a research-stage composition within the family of rare-earth sulfides and alkali-metal chalcogenides, with potential applications in solid-state ionics, photovoltaics, and energy storage systems where mixed ionic-electronic conduction is desired. While not yet commercialized at scale, compounds in this materials family are of interest for their tunable bandgap, thermal stability, and the possibility of fast ion transport pathways that could enable next-generation battery electrolytes or optoelectronic devices.

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.
