Li4 Er4 O8
ceramic· Li4 Er4 O8
Li4Er4O8 is a mixed rare-earth lithium oxide ceramic compound combining lithium with erbium, an uncommon lanthanide element. This material is primarily of research and developmental interest rather than established in high-volume industrial use; it belongs to the family of rare-earth oxide ceramics being explored for advanced applications where ionic conductivity, thermal stability, or unique optical properties are required. The combination of lithium and erbium oxides makes this compound potentially relevant for solid-state battery electrolytes, photonics, or specialized thermal/structural applications where rare-earth oxides offer advantages over conventional ceramics.

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.
