· Er2 Cl2 O2

Er2Cl2O2 is an erbium-based oxychloride ceramic compound combining rare-earth erbium with chloride and oxide anions, creating a mixed-valence ceramic structure. This material exists primarily in research and specialized contexts rather than widespread industrial production; erbium compounds are valued in photonics, optical communications, and high-temperature applications where rare-earth elements provide unique electronic and thermal properties. The oxychloride chemistry makes this compound of interest for solid-state chemistry research, potential optical fiber dopants, and advanced ceramic matrix applications where erbium's luminescent properties or thermal stability could 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.
