UN

Uranium nitride (UN) is a ceramic compound belonging to the refractory nitride family, characterized by high density and strong interatomic bonding typical of transition metal nitrides. It is primarily investigated for advanced nuclear fuel applications and high-temperature structural uses where extreme thermal stability and radiation resistance are critical. UN offers potential advantages over conventional uranium dioxide fuel in nuclear reactors due to its higher thermal conductivity and fissile density, making it attractive for next-generation reactor designs, though it remains largely in the research and development phase rather than widespread commercial deployment.
