Abstract

Abstract

One of the most important procedures for fabrication of Uranium Nitride fuel is the synthesis of uranium nitride powders with high purity and good sintering ability.The carbothermic synthesis process of uranium nitride powder by reaction of UO₂ powder with Carbon and nitrogen has been studied,and the effect of mole ratio of carbon to uranium,atmosphere controlling,reaction temperature and time on the content of uranium nitride powder has been discussed in this paper.The results show that uranium nitride powder with higher purity can be fabricated by using suitable mole ratio of carbon to uranium（2.3-2.4） and reaction procedures.
