· JVASP-18259· UNi2P2

UNi₂P₂ is an intermetallic compound in the uranium-nickel-phosphorus system, representing a transition metal phosphide with potential applications in advanced materials research. This material belongs to the family of refractory intermetallics and phosphide ceramics, which are of interest for high-temperature structural applications and catalytic uses. While primarily a research compound rather than a widely commercialized engineering material, uranium-containing intermetallics are investigated for nuclear fuel applications, specialized alloys, and as model systems for understanding phase stability in complex metal-phosphide systems.
