· JVASP-65654· BaTlSe2

BaTlSe₂ is a ternary ceramic compound composed of barium, thallium, and selenium—a mixed-halide chalcogenide material in the family of complex metal selenides. This is a research-phase compound rather than an established industrial material, studied primarily for its potential in thermoelectric energy conversion and semiconductor applications where the combination of heavy elements and layered crystal structure can create favorable electron transport properties.

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.
