· JVASP-14867· ThNi2

ThNi2 is an intermetallic compound in the thorium-nickel binary system, representing a hard ceramic-like metal phase typically studied for high-temperature structural applications. This material belongs to the family of rare-earth and actinide intermetallics, which are primarily investigated in research settings for nuclear fuel cladding, high-temperature aerospace components, and specialized refractory applications where conventional alloys reach their thermal limits. ThNi2 is notable for its potential to combine metallic conductivity with ceramic-like stiffness and thermal stability, though its practical adoption remains limited due to thorium's radioactive nature, processing challenges, and the availability of competing advanced superalloys and composites for most industrial applications.
