Uranium nitride UN is a ceramic compound used as nuclear fuel in nuclear test reactors, because it has similar properies like uranium dioxide or uranium carbide. It can be synthesized by the reaction of nitrogen with uranium at 700 K. .[2] Uranium nitride is also formed as a product of Uranium combustion in air.
