Investigations on Obtaining Spherical Uranium Dicarbide Particles from Uranium Dioxide.

Abstract

The preparation of UC2 in the form of dense spherical particles is described. The applied method is based on heating UO2 particles in a graphite powder bed in a furnace with a graphite heating element up to 2500 deg. C, in Ar atmosphere under normal pressure. Starting materials such as UO2 prepared by sintering, unsintered UO2 and UO2 agglomerated without additions containing C substances are used. The influence of the UO2 on the particle size distribution and the product quality is examined. The dependence of free C content and product density on the spherical particles specific surface (diameter) of the product is established and explained. Some of the problems are discussed concerning the increase of the process scale. (Author)
