Er2S3
ceramic· JVASP-45361· Er2S3
Er2S3 is an erbium sulfide ceramic compound belonging to the rare-earth chalcogenide family, which combines erbium (a lanthanide element) with sulfur to form a stable ionic ceramic. While primarily of research interest, Er2S3 and related rare-earth sulfides are investigated for potential applications in high-temperature optics, luminescent materials, and specialized electronic devices where rare-earth-doped ceramics offer unique optical or thermal properties. This material represents an experimental composition within a family of compounds studied for niche applications requiring specific combinations of thermal stability, optical transparency in infrared wavelengths, and rare-earth functionality.

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.
