· Rb1 Fe2 As2

RbFe₂As₂ is an iron-based superconductor belonging to the 122-family of layered pnictide compounds, characterized by alternating layers of iron-arsenide sheets and alkali-metal spacer layers. This material is primarily of research interest for fundamental studies of unconventional superconductivity and quantum phase transitions rather than current commercial applications; it exhibits superconducting properties at cryogenic temperatures and has been instrumental in understanding the mechanisms of iron-based superconductivity, which differ fundamentally from conventional BCS superconductors. Engineers and materials scientists study this compound family to advance knowledge of high-temperature superconductors and explore potential future applications in power transmission, magnetic levitation, and quantum devices.

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.
