· JVASP-64062· Ba4TaSe

Ba₄TaSe is an ternary ceramic compound containing barium, tantalum, and selenium, belonging to the family of mixed-metal chalcogenides. This is a research-phase material primarily studied for its potential in thermoelectric and electronic applications rather than established industrial production. Interest in this compound stems from its crystal structure and electronic properties within the broader class of chalcogenide ceramics, which are investigated as alternatives to traditional semiconductors and thermoelectric materials, particularly where high-temperature stability or specific band-gap characteristics are needed.

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.
