· Pr1 Al8 Fe4

Pr₁Al₈Fe₄ is an intermetallic compound combining praseodymium, aluminum, and iron, belonging to a family of rare-earth aluminum-iron compounds with semiconductor characteristics. This material is primarily of research interest for investigating magnetic, electronic, and structural properties in rare-earth intermetallics, with potential applications in advanced functional materials where controlled electronic behavior and thermal stability are needed. The combination of rare-earth and transition-metal elements makes it notable for exploring new property combinations in permanent magnets, magnetocaloric systems, and high-temperature structural applications, though industrial adoption remains limited pending further development.

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.
