· La3Te3.65Sb0.35

La3Te3.65Sb0.35 is a rare-earth chalcogenide ceramic compound combining lanthanum with tellurium and antimony. This is primarily a research material under investigation for thermoelectric applications, where the mixed-anion composition is designed to optimize phonon scattering and reduce thermal conductivity while maintaining electrical performance. The material belongs to the family of skutterudite-related and filled-tetrahedral compounds of interest for solid-state heat-to-electricity conversion, particularly in mid-range temperature regimes where conventional thermoelectrics face limitations.

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.
