Oxidative ammonolysis of uranium(IV) fluorides to uranium(VI) nitride

Actinide nitrides, in particular UN, are being considered as fuel types for advanced reactor systems. Here, we demonstrate a low-temperature synthesis route on uranium that could be developed into a commercial fabrication process for UN and mixed actinide nitride fuels. UN was successfully synthesized from UO2 by first reacting with NH4HF2 in a ball mill at 20 C to form tetravalent ammonium ura...

Microscopic Characterization of Uranium Nitrides Synthesized by Oxidative Ammonolysis of Uranium Tetrafluoride

The oxidative ammonolysis route was used to synthesize three uranium nitrides, UN2, U2N3, and UN, using UF4 as the starting material. Powder XRD analysis showed the UN2 and U2N3 products to contain less than 1.0 wt % uranium oxides. UO2 level was identified to be 5.0 (0) wt % in the UN product as it is made, but this level increases upon exposure to air. The morphology of these nitrides was stu...

Preparation of Ethylenediamine by Ammonolysis of 1,2-Dichloroethane in Nonaqueous Media

Kinetic parameters of the ammonolysis reaction of dichloroethane in nonaqueous media are studied and the optimum reaction conditions are reported. A suitable reactor for running the reaction under high pressure in the range of 50 to 500 °C is designed. Kinetic behaviours of the system is studied and other reaction parameters such as rate constant, kinetic order, and activation energy are de...

Evaluation of nanocrystalline Sn3N4 derived from ammonolysis of Sn(NEt2)4 as a negative electrode material for Li-ion and Na-ion batteries

Bulk nanocrystalline Sn3N4 powders were synthesised by a two step ammonolysis process followed by washing with dilute acid. Their performance as Li-ion and Na-ion battery negative electrodes was assessed by galvanostatic cycling in half cells vs. the metal, giving good performance in both cases and remarkable stability in the sodium cells. The effect of carboxymethyl cellulose and sodium algina...
