· JVASP-37752· PmYAl2

PmYAl2 is an intermetallic compound combining promethium (Pm) and yttrium (Y) with aluminum, representing an experimental rare-earth aluminum system. This material belongs to the family of rare-earth intermetallics being investigated for potential high-temperature applications and advanced aerospace or nuclear contexts, though it remains largely in research and development phases. Engineers would evaluate this compound primarily for theoretical high-temperature stability or specialized nuclear applications where rare-earth elements offer unique thermal or radiation properties unavailable in conventional alloys.
