· JVASP-123227· Er3O

Er3O is a rare-earth oxide ceramic composed primarily of erbium and oxygen, belonging to the family of lanthanide oxides used in advanced materials research. This material is of primary interest in photonics, nuclear, and high-temperature applications, where rare-earth oxides serve as host matrices for luminescent dopants, neutron absorbers, or refractory components. Engineers consider Er₂O₃-based ceramics when seeking materials with high thermal stability, optical transparency in the infrared spectrum, or specialized nuclear shielding properties that conventional oxides cannot provide.

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.
