Er2S2O
ceramic· JVASP-96631· Er2S2O
Er₂S₂O is an erbium oxysulfide ceramic compound combining rare-earth erbium with sulfur and oxygen constituents. This material belongs to the family of rare-earth oxychalcogenides, which are primarily of research interest for their potential in photonic and electronic applications where the rare-earth dopant properties can be leveraged. While not yet widely established in mainstream engineering applications, oxysulfide ceramics are being explored for optical coatings, luminescent materials, and potential high-temperature ceramic matrix applications where erbium's infrared emission characteristics may be valuable.

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.
