· JVASP-12360· In2FeS4

In₂FeS₄ is an ternary metal sulfide compound combining indium, iron, and sulfur in a stoichiometric ratio, belonging to the family of mixed-metal chalcogenides. This material is primarily of research interest rather than established commercial use, with potential applications in semiconductor, photovoltaic, and thermoelectric device development where mixed-valency metal sulfides show promise for band-gap engineering and charge-carrier control. Engineers would investigate this compound in exploratory material design for optoelectronic or energy-conversion applications where the combination of earth-abundant iron with indium's semiconducting properties could offer cost-performance trade-offs compared to simpler binary sulfides.

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.
