USi₂ (uranium disilicide) is an intermetallic ceramic compound combining uranium with silicon in a 1:2 stoichiometric ratio. It belongs to the family of transition metal silicides and represents a material of primarily research and nuclear engineering interest rather than widespread commercial use. This compound is explored for specialized high-temperature applications and nuclear fuel contexts where its unique combination of metallic and ceramic characteristics—including high density and stiffness—may offer advantages in extreme environments.
