· Sm3Te4

Sm₃Te₄ is a rare-earth telluride semiconductor compound combining samarium with tellurium in a fixed stoichiometric ratio. This material belongs to the rare-earth chalcogenide family and is primarily of research interest rather than established in high-volume production; it is studied for potential applications in thermoelectric energy conversion and solid-state electronic devices where the combination of rare-earth elements and tellurium offers tunable electronic and thermal transport properties.

Export Control

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.
