Electroconductivity, electroluminescence spectra, and activation of molten MCl2+KCl (M=Ca, Sr, Ba) in high electric fields

Structural Relaxation in the Activated Molten Chloride Electrolytes of Polyvalent Metals

“…Full pulse duration excludes introduction of electrolysis products into the electrolyte and it's any significant overheating. This analysis and electroluminescence spectra of molten salts [5,6,10] confirm that regularities observed in behavior of the electrolytes, in strong fields that we used, take place with maintaining the electrolytic nature of the conductance.…”

“…After activation of the magnesium electrolyte MgCl 2 -NaCl-KCl by series of pulses with the amplitude of voltage of 8 kV EMF of the cell became equal to 1630 mV. Consequently, the potential of the magnesium electrode in its activated chloride electrolyte became more positive by 15.6% [5,6]. The results above allow expecting that the decomposition potentials of metal chlorides in non-equilibrium state would be less than in "equilibrium" state.…”

“…It is known that the Wien effect has served as the experimental proof of the validity of the Debye-Huckel-Onsager theory of electrolyte solutions and is used as the research method in physical chemistry. Prior to our publications, for example [4,5], in the literature has not been articles on the Wien effect in molten salts. We have established the regularity in dependence of conductivity of molten salts on electric field strength (EFS) by analyzing the waveforms of pulsed ( s  ) discharges in them.…”

Intensification of electrochemical properties of the molten chloride electrolytes of the cerium subgroup lanthanides

“…To this end, we have constructed high-voltage setup for pulsed conductometry. The electric circuit of our experimental setup, the measuring cell, and the technique of determining the electrical conductivity of an electrolyte in strong electric fields were described in our earlier works (see, e.g., [3,4]). The setup involves the digital pulsed memory oscilloscope ASK-8 which records waveforms of attenuated current and voltage during the pulse discharge in a studied sample.…”

“…For better understanding the structure of equilibrium molten electrolytes and improving the chemical and electrochemical technologies, their properties should be studied in a non-equilibrium state, which can be achieved by various external influences, for example, by the action of strong electric pulses [2]. We have found that electrical conductivity of molten alkaline-earth chlorides and their mixtures with alkaline chlorides increase with increasing external electric field strength (EFS) and strive to achieve the limiting high-voltage values in the fields of the order of 1 MV/m [3], in the same way as in the Wien effect in the aqueous electrolyte solutions.…”
