| Abstract | OBJECTIVES We proposed a method for the preparation of uranium oxide concentrate molding powder using dry organic plasticizers for subsequent compression and recovery in a carbon atmosphere to the uranium dioxide with set-up stoichiometric ratio. METHODS A number of dry softeners has been selected, their some physical and chemical properties are defined, their influence on physical and chemical and technological properties of uranium protoxide oxide powder is defined, the assessment of the greasing and binding abilities of softener is made. RESULTS Results of definition of the added softener necessary amount, proceeding from chemistry of restoration process of uranium protoxide oxide by decomposition products are presented. |
