· JVASP-100789· UNb

UNb is a uranium-niobium intermetallic compound belonging to the refractory metal alloy family, characterized by extremely high density and thermal stability. This material is primarily of research interest for nuclear applications, aerospace propulsion systems, and high-temperature structural components where its exceptional density and refractory properties offer advantages over conventional superalloys, though its radioactive nature and processing complexity limit widespread industrial adoption.
