· Ce2 O3

Cerium oxide (Ce₂O₃) is a rare-earth ceramic semiconductor material, part of the lanthanide oxide family that exhibits mixed-valence behavior and ionic conductivity properties. This material appears primarily in research and advanced technology applications rather than commodity manufacturing, including solid oxide fuel cells, oxygen sensors, catalytic converters, and polishing compounds where its oxygen storage capacity and redox activity are leveraged.

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.
