· Ba2 Y1 Tl1 Fe2 O7

Ba₂Y₁Tl₁Fe₂O₇ is an experimental mixed-metal oxide semiconductor belonging to the family of complex perovskite and pyrochlore-related structures. This compound combines barium, yttrium, thallium, and iron oxides in a layered framework, representing research-phase material exploration for functional ceramics rather than an established industrial product. The material is notable within the solid-state chemistry community for its potential in high-temperature semiconducting applications, magnetic property engineering, and multiferroic device research, where the combination of rare-earth (Y) and post-transition (Tl) elements with iron enables tunable electronic and magnetic behavior.

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.
