· JVASP-75874· LaFeAs

LaFeAs is an iron-based superconductor compound belonging to the 1111-type layered pnictide family, discovered as a high-temperature superconductor with critical temperatures around 26–32 K depending on doping and processing. This material is primarily investigated in condensed matter physics and materials research rather than conventional engineering applications, offering insights into unconventional superconductivity mechanisms distinct from copper-oxide ceramics. Engineers and researchers examine LaFeAs and its derivatives for fundamental studies of superconducting phenomena and potential future applications in power transmission, magnetic shielding, and quantum computing, though practical deployment remains limited to specialized laboratory and experimental settings.

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.
