· JVASP-100854· PmSe2

PmSe₂ is a layered transition metal dichalcogenide ceramic compound composed of promethium and selenium. This material belongs to the family of 2D materials and Van der Waals solids, which are primarily studied in advanced research contexts for their unique electronic, optical, and mechanical properties arising from their layered crystal structure. While not yet widely deployed in mature industrial applications, dichalcogenide materials like PmSe₂ are being investigated for potential use in next-generation electronics, photonics, and energy storage devices due to their tunable bandgaps and strong light-matter interactions; however, the radioactive nature of promethium presents significant practical and safety challenges that limit real-world development compared to more readily accessible dichalcogenides based on molybdenum, tungsten, or other stable elements.

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.
