· JVASP-150395· Er4I5

Er4I5 is an erbium iodide ceramic compound belonging to the rare-earth halide family, characterized by a high density and ionic crystal structure typical of lanthanide halides. This material is primarily investigated in research contexts for specialized optical, electronic, and thermal applications where rare-earth dopants or host matrices are required. Er4I5 represents the type of rare-earth ceramic that bridges fundamental materials science and potential device applications, though industrial adoption remains limited compared to more established rare-earth compounds.

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.
