· JVASP-152230· LaTeAs

LaTeAs is a ternary ceramic compound composed of lanthanum, tellurium, and arsenic elements. This material belongs to the family of rare-earth chalcogenide ceramics and remains largely in the research domain, where it is being investigated for potential semiconductor and optoelectronic applications due to the electronic properties imparted by its lanthanide constituent. Interest in LaTeAs centers on fundamental studies of rare-earth pnictide-chalcogenide materials for next-generation electronic devices, though industrial deployment remains limited compared to more mature ceramic systems.

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.
