· Li1 Er2 Ru1

Li₁Er₂Ru₁ is an experimental ternary intermetallic compound combining lithium, erbium (a rare-earth element), and ruthenium. This material belongs to the emerging class of rare-earth–transition metal semiconductors being investigated for thermoelectric and quantum materials applications. While not yet in widespread commercial use, compounds in this family are of research interest for energy conversion devices and materials with unusual electronic properties, where the combination of rare-earth and noble-metal elements can produce tunable band structures and potentially useful transport phenomena.

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.
