“…Today, there is no clear understanding of the processes occurring in solutions of polar dielectrics under the influence of an asymmetric electric field. Earlier it was theoretically shown 10,11 that the total energy of a solvated ion-cluster, characterized by the state of the system, consists of the following: the energy of translatory motion of the entire cluster; the electron energy, determined by the quantum state of the electron shells of the ion and the solvent molecules associated around the ion; the vibrational energy, caused by the oscillation of the ion and the solvate shell relative to each other; 4 and the rotational energy, corresponding to the rotation of the entire cluster or its parts relative to each other. 5 Wherein, the inertial properties of clusters can differ for reasons of the difference in the ion masses while the coordination numbers are equal.…”

This paper shows the selective drift of cationic aqua complexes of chloride salts of metal ions in aqueous solutions under the exposure an asymmetric electric field (100 Hz, 750/150 V). The spatial distribution of Ce 3+ and Ni 2+ cations was demonstrated, and the maximum cation separation coefficients in the longitudinal section of the inter-electrode space were calculated for the stationary and circulating solution for different exposure durations of the electric field and solution circulation rates. A decrease in the relative concentration of cations was observed when moving from top down of the experimental cell, while the direction of cation drift along the sectional plane was independent of the distance from electrodes, the solution circulation rate, and nature of metal. It was established that while the solution moved from the grounded electrode to the potential electrode along the bottom and top parts of the sections, there was a decrease of concentrations of both cations in the central part of the cell and an increase near the electrodes. On the basis of the obtained data, the optimal points of sampling and drop were determined. The calculated maximum separation coefficients of Ce 3+ and Ni 2+ ions were 1.200 ± 0.108 and 1.036 ± 0.025, for the stationary and circulating solution at a rate of 7 L•h −1 , respectively.

“…Major disadvantages of applied plasma technologies for synthesis of fuel compounds (FC) from nitric solutions are high energy costs (up to 4.0 MW•h/t) and necessity of additional hydrogen reduction for obtaining compounds of required composition [6][7][8][9].…”

The process of plasma-chemical synthesis from water-organic nitrate solutions of uranium and magnesium of fuel compositions including a matrix of magnesium oxide with a high thermal conductivity and low neutron absorption is investigated. The compositions of the solutions, including acetone (ethanol), as well as the regimes that providing the direct synthesis of "UO2-MgO" fuel compositions of different concentrations in air plasma are determined. The calculation of their thermal conductivity and comparison with experimental data are presented.
