· Si2 Fe2 Tm1

Si₂Fe₂Tm₁ is an intermetallic compound combining silicon, iron, and thulium (a rare-earth element) in a defined stoichiometric ratio. This is a research-phase material rather than a production commodity; it belongs to the family of rare-earth iron silicides, which are investigated for potential applications in high-temperature electronics, magnetic devices, and advanced semiconductor applications where rare-earth doping can modify electronic or magnetic properties. Engineers would consider this material primarily in experimental contexts where the combination of iron's ferromagnetic character, silicon's semiconducting properties, and thulium's rare-earth contributions offer a unique property set not available in conventional alloys or simple binaries.

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.
