· JVASP-102317· Y2AsS

Y2AsS is an yttrium arsenic sulfide ceramic compound belonging to the family of rare-earth chalcogenides. This material is primarily of research and development interest rather than established in high-volume industrial production, with potential applications in solid-state electronics, photonics, and specialized optical systems where rare-earth compounds offer unique electronic and optical properties. The combination of yttrium with arsenic and sulfur makes it noteworthy for exploring semiconductor or photonic behavior in systems where conventional oxides or nitrides are unsuitable.

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.
