· JVASP-123230· Er3Pa

Er₃Pa is a rare-earth intermetallic ceramic compound combining erbium and protactinium, representing an advanced materials research composition with potential applications in high-temperature and nuclear environments. While not widely commercialized, this material belongs to the family of rare-earth intermetallics studied for their exceptional thermal stability and potential use in extreme service conditions where conventional ceramics reach performance limits. Engineers would consider Er₃Pa primarily in specialized research and development contexts for nuclear fuel elements, high-temperature structural applications, or advanced reactor technologies where the unique properties of rare-earth–actinide combinations offer advantages over standard ceramic alternatives.

Regulatory Screening

Environmental

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.
