· Ba1 Fe2 S4

Ba₁Fe₂S₄ is an iron-barium sulfide semiconductor compound belonging to the ternary chalcogenide family. This material is primarily of research interest rather than established industrial use, studied for its potential in photovoltaic, thermoelectric, and optoelectronic applications where earth-abundant transition metals and tunable band gaps are desirable. The material represents an alternative to conventional semiconductors like CdTe or CIGS, with potential relevance in next-generation solar cells and energy conversion devices where cost and elemental abundance are critical drivers.

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.
