· JVASP-66092· Ba4TlFe

Ba₄TlFe is an intermetallic compound combining barium, thallium, and iron elements, belonging to the class of ternary metal systems. This is a research-phase material studied primarily for its crystallographic and electronic properties rather than established industrial production. The Ba-Tl-Fe system is of academic interest in solid-state chemistry and materials physics for understanding phase diagrams, crystal structure formation, and potential magnetic or electronic behavior in multi-component metallic systems; however, it has not achieved widespread engineering adoption due to thallium's toxicity concerns, scarcity, and cost, limiting practical applications compared to conventional iron-based alloys and intermetallics.

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.
