Er4Sb3
ceramic· JVASP-58293· Er4Sb3
Er4Sb3 is an intermetallic ceramic compound composed of erbium and antimony, belonging to the rare-earth pnictide family of materials. This compound is primarily of research interest for its potential in thermoelectric and electronic applications, where rare-earth intermetallics offer tunable band structures and phonon-scattering mechanisms. Er4Sb3 and related rare-earth antimonides are investigated for converting waste heat to electricity and for solid-state electronic devices where the combination of rare-earth and pnictide chemistry can provide advantageous thermal and electrical transport properties compared to conventional semiconductors.

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.
