· JVASP-34479· Ba4Fe2S4I5

Ba4Fe2S4I5 is an experimental mixed-halide sulfide compound combining barium, iron, sulfur, and iodine—a material class of interest in solid-state chemistry and materials research rather than established industrial production. This compound belongs to the family of chalcogenide-halide hybrids, which researchers are investigating for potential applications in optoelectronics, photovoltaics, and solid-state ionics due to their tunable electronic and ionic properties. The material remains primarily in the research phase; its practical advantages over conventional alternatives would depend on its specific optical bandgap, electronic conductivity, and thermal stability relative to established semiconductors or solid electrolytes.

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.
