НИКЕЛЬ ХРОМ -- НИКЕЛЬ АЛЮМИНИЙ -- Li -- Li2CO3-K2CO3 -- K2CO3 -- K -- Li2CO3 -- Ni -- Al -- Cr -- СМАЧИВАНИЕ
Аннотация: The change of the interfacial free energy at the interfaces betweennickel-aluminium and nickel-chromium alloys of varius composition and eutectic Li2CO3-K2CO3 melts was studied as a function of potential. Experiments were performed in oxidizing, reducing, and inert atmospheres at 910-940 K; the method of meniscus weight was used. It was found that the contact angle decreases from 88 degrees to 0 degrees when one passes from a reducing atmosphere to a neutral and then to an oxidizing one. A region of potentials characterized by the partial charge transfer from the adsorbed oxygen anions to an electrode was discovered. This charge transfer results in the formation of complex anions and in the reversal of the surface charge of alloys. The pattern of the change in the values of the contact angles and potentials at the point of zero charge with the composition of alloys is revealed. The results are discussed from the viewpoint of the interaction between the components of the alloy

ТЕРМОДИНАМИКА -- ИТТЕРБИЙ
Аннотация: This work presents the electrochemical study of Yb(III) ions in molten alkali metal chlorides in the temperature range 723–1073 K. Transient electrochemical techniques such as linear sweep, cyclic and square wave voltammetry, and potentiometry at zero current have been used to investigate the reduction mechanism, transport parameters and thermodynamic properties of the reaction YbCl2 + 1/2Cl2 = YbCl3 The results obtained show that the reduction reaction Yb(III) + e? Yb(II) is reversible being controlled by the rate of the mass transfer. The diffusion coefficient of [YbCl6]3? complex ions has been determined at different temperatures in the fused eutectic LiCl–KCl, the equimolar NaCl–KCl and the CsCl media. The apparent standard potential of the soluble–soluble redox system Yb(III)/Yb(II) has been obtained by cyclic voltammetry. The influence of the nature of the solvent on the electrochemical and thermodynamic properties of ytterbium compounds is discussed.

MOLTEN CHLORIDES -- ХРОНОПОТЕНЦИОМЕТРИЯ -- ВОССТАНОВЛЕНИЕ -- КОЭФФИЦИЕНТ ДИФФУЗИИ -- ТЕРМОДИНАМИЧЕСКИЕ СВОЙСТВА
Аннотация: This work presents the electrochemical study of Cm(III) in fused NaCl–2CsCl eutectic in the temperature range 823–1023 K. Transient electrochemical techniques such as cyclic, differential pulse and square wave voltammetry, and chronopotentiometry have been used in order to investigate the reduction mechanism of curium ions up to the metal. The results obtained show that the reduction reaction takes place in a single step . The diffusion coefficient of [CmCl6]3- complex ions was determined by cyclic voltammetry at different temperatures by applying the Berzins–Delahay equation. The validity of the Arrhenius law was also verified and the activation energy for diffusion was found to be 44.46 kJ/mol. The apparent standard electrode potential of the redox couple Cm(III)/Cm(0) was found by chronopotentiometry at several temperatures. The thermodynamic properties of curium trichloride have also been calculated.????

Аннотация: The influence of sodium (Na) additions with different chemical natures (sodium peroxide Na2O2 and sodium chloride NaCl on the mechanism and kinetics of aluminum Al corrosion was investigated. Auger electron spectroscopy, x-ray photoelectron spectroscopy, and x-ray structure spectroscopy were used to analyze the corrosion products. Na2O2 promoted formation of more compact, less defective films. At high temperature, the introduction of peroxide into the salt phase resulted in the emergence of different oxigen (O) ions and a film with higher O content NaCl additions destroyed the coating through formation of pits and local solutions of oxide layers. The greater the concentration of active ions was, the less the initial depassivation potential was. Increases in anodic polarization and concentrations of chloride ions (Cl-) diminished induction time. Films consisted only of alpha-LiAlO2, a crystal modification of lithium aluminate

MOLTEN SALT FLUORIDES -- BERYLLIUM REFERENCE ELECTRODE -- REDOX POTENTIAL
Аннотация: Existing designs of reference electrodes for potentiometric measurements in fluoride melts do not meet basic requirements of the long exposure corrosion tests to be performed. A new diaphragm-free three-electrode meter with a nonstationary (dynamic) beryllium reference electrode for the redox potential measurements was developed. Optimum conditions of forming dynamic beryllium reference electrode were determined in the laboratory tests in isothermal cell. The device for redox potential measurement was designed and it was shown that it is highly sensitive to changes redox potential within ±5 mV. Reliability and efficiency of diaphragm-free device with dynamic reference electrode was confirmed in the thermal convection corrosion loop operating more than 1200 h with molten 15LiF–58NaF–27BeF2 mixture (mol%) at a maximum temperature of about 700 °C.????

POTENTIAL
Аннотация: Cost remains a major barrier for commercial success of SOFC. SRI evaluated a cost competitive SOFC manufacturing process developed by Russian researchers who work in this field since the late 1950s. The process is based on thermal decomposition of organo-metallic compounds. Cost savings are possible because: (a) the deposition process is performed at atmospheric pressure, (b) all layers (electrolyte, interface layers, and anode) are deposited sequentially within the same reactor, and (c) the raw materials and equipment are inexpensive. Electrochemical test cells (sections of a single SOFC element) prepared at the IHTE have been analyzed and tested at SRI International. Each cell consists of LSM cathode, YSZ electrolyte, and platinum paste anode. Composition and microstructure were determined by SEM examination and x-ray diffraction. The electrolyte had a 0.92ZrO2+0.08Y2O3 composition with thickness 17-80 micrometers; it had cubic fluoride type structure similar to compact samples of the same material. Size of crystallites at the external layer of the electrolyte was 1-9 micrometers. In SRI's testing, a power density of ?0.45 W/cm2 was measured at 900°C. The power produced by elements under a constant load was stable for 1,500 hours of continuous operation, and the fuel elements survived multiple on/off cycles. Examination with a scanning electron microscope (SEM) before and after the tests of the elements' microstructures showed no significant transformation. SRI concluded that the core technology of the Russian SOFC generators is reliable, has high technical potential, and may offer strong competitive advantage for producing commercial products at a cost of under $500/kW.

Аннотация: This work presents the influence of electrode material nature on the mechanism of cathodic reduction of ytterbium (III) ions in fused NaCl–KCl–CsCl eutectic at the temperature range 723–1073 K. Transient electrochemical techniques such as linear sweep, cyclic, semi-integral and square wave voltammetry, and potentiometry at zero current have been used in order to investigate the reduction mechanism of ytterbium ions on inert and active working electrodes, transport parameters and thermodynamics properties of the ytterbium compounds. The influence of the material of working electrode on the mechanism of the cathode process was determined. The results obtained show that the reduction reaction on W electrode is reversible being controlled by the rate of the mass transfer. The diffusion coefficient of [YbCl6]3- complex ions was calculated at different temperatures and the apparent standard electrode potential of the soluble–soluble redox system Yb3+/Yb2+ was obtained. The reduction reaction of ytterbium (III) ions on Al active electrode was investigated. Al2Yb and Al3Yb alloys are formed during the polarization on the surface of working electrode

ОКСИД ХРОМА -- АНОД -- ЭЛЕКТРОЛИЗ -- РАСТВОРЕНИЕ
Аннотация: In order to fabricate oxide-metallic composites with the composition 25.3NiO-41.2Fe2O3-13.5Cr2O3-20.0Cu (wt %), the temperature and duration of sintering (1350°C, 30 min) that ensure the formation of the solid solution of chromium oxide in nickel ferrite have been determined. This material is tested as an anode for the electrolysis of the low-temperature solution with the composition 12.0NaF-36.8KF-51.2AlF3 (wt %), which was saturated with Al2O3 (t = 800°C). The amount of gaseous oxygen evolved on the anode was measured. It is shown that the main reaction on an anode at current density i = 0.015–1.0 A cm−2 is the oxidation of oxygen-containing anions from a melt with the formation of gaseous O2 and a substantial increase in the oxidation rate of the composite anode is observed at i > 1.0 A cm−2. The voltage across the electrolyzer (4.5 ± 0.5 V) and the anodic potential (2.43 ± 0.2 relative to the Al reference electrode) during a prolonged experiment (for 89 h, i = 0.4 A cm−2) indicate a stable and acceptable electrical conductivity of the material, while the dissolution rate, which was calculated by the weight loss (0.6 kg/yr) and volume loss (0.7 cm/yr), satisfy the requirements to inert anodes.

Аннотация: This work presents the results of a study of the Tm3+/Tm2+ couple redox potentials vs. Cl–/Cl2 reference electrode at the temperature range (833 to 1073) K in molten equimolar NaCl–KCl and NaCl–2CsCl eutectic by direct potentiometric method. Initial concentrations of TmCl3 in solvents did not exceed 5.0 mol%. Apparent standard redox potentials of the couples were determined in different solvents. Basic thermodynamic properties of the reaction were calculated. The dependence between the apparent standard redox potentials of the couples and the ionic potential of the solvents was established.
