Pm2O3
semiconductor· Pm2O3
Pm₂O₃ is a rare-earth oxide semiconductor compound based on promethium, belonging to the lanthanide oxide family. This material is primarily of research and specialized industrial interest rather than mainstream commercial use, as promethium is a radioactive element with limited natural availability. Its applications are confined to niche sectors where its semiconductor properties, combined with potential luminescent or thermal characteristics, can be leveraged in controlled environments.

Export Control
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.
