· Fe1.98Sn0.02O3

Fe1.98Sn0.02O3 is a tin-doped iron oxide ceramic, a modified hematite (Fe2O3) system where approximately 1% of iron sites are substituted with tin. This is primarily a research material designed to investigate how aliovalent dopants affect the electronic, optical, and catalytic properties of iron oxide semiconductors, rather than a widely deployed industrial material. The tin doping is studied for potential applications in gas sensing, photocatalysis, and electrochemical devices where enhanced charge carrier mobility and modified band structure offer advantages over undoped hematite.

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.
