Uranium nitride refers to a family of several ceramic materials: uranium mononitride (UN) uranium sesquinitride (U2N3) and uranium dinitride (UN2). Nitride refers to -3 oxidation state of the nitrogen bound to the uranium. The nitrogen gets its -3 oxidation state from the nature of the triple bond that uranium forms with nitrogen in uranium nitride compounds.
