· JVASP-24288· Er2Te5O13

Er₂Te₅O₁₃ is an erbium tellurite ceramic compound combining rare-earth and chalcogenide chemistry. This material is primarily of research and specialty interest rather than established industrial production, with potential applications in photonics and optical systems where erbium's luminescent properties and tellurite's infrared transparency can be leveraged.

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.
