· JVASP-50848· Pr2S2O

Pr2S2O is an experimental rare-earth oxysulfide ceramic composed of praseodymium, sulfur, and oxygen. This material belongs to the family of mixed-anion rare-earth compounds, which are primarily investigated in research settings for their potential in advanced optical, electronic, and thermal applications. The oxysulfide structure—combining both oxide and sulfide anion frameworks—offers a platform for tuning material properties like bandgap and crystal structure in ways that single-anion ceramics cannot easily achieve, making it of interest to materials scientists exploring next-generation functional 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.
