ТЕПЛОЕМКОСТЬ -- КАРБОНАТЫ
Аннотация: This article reports the experimental data on the key thermal properties of some molten salt eutectics containing lithium, sodium, potassium, zirconium, and thorium fluorides. Their melting points, enthalpies of melting, heat capacities were measured using STA 449C Jupiter® synchronous thermal analyzer while the thermal conductivity was determined by the steady-state method of coaxial cylinders. The validity of the empirical equations proposed for estimating the isobaric heat capacity (cp) and thermal conductivity (?) of the possible MSR coolants and fuels is discussed.

ЭЛЕКТРОПРОВОДНОСТЬ -- ЩЕЛОЧНОЗЕМЕЛЬНЫЕ МЕТАЛЛЫ -- ЛЕГИРОВАНИЕ
Аннотация: The present work aims at the investigation of Ln0.2Ce0.8O2−δ (where Ln = Sm, La, Gd) structural and electrical properties when in the Ln sub-lattice, Ba2+ and Sr2+ with ionic radii 1.42 and 1.26 Å, respectively, are introduced. The conductivity measurements were held both in air and in H2 + 3%H2O atmosphere using the 4-probe dc technique at the temperature range of 600–900 °C. Among all the samples, the highest value of electrical conductivity is obtained in the case of (Sm0.75Sr0.2Ba0.05)0.2Ce0.8O2−δ, both in air and in hydrogen atmosphere. In the case of H2 + 3%H2O the conductivity of the co-doped compounds increases in comparison with air. Moreover, the dependence of conductivity on the oxygen partial pressure, measured at the range of 0.21–10−22 atm, showed that the electrolytic area of alkaline-earth metals doped Ln0.2Ce0.8O2−δ is considerably enhanced, as predicted by the theory. Finally, by comparing the thermal expansion coefficients of the different materials (TEC), the thermo-mechanical compatibility between the co-doped and the other cell components was also investigated.

Аннотация: The effect of calcium fluoride on liquidus temperatures of the cryolite melts with a low cryolite ratio (CR) was studied. The systems KF-NaF-AlF3 and KF-LiF-AlF3 with CRs of 1.3, 1.5, and 1.7 have been investigated. The liquidus curves of systems containing CaF2 are different and depend on the K/(K + Na) and K/(K + Li) ratios. In potassium cryolite with CRs of 1.3 and 1.5, the calcium fluoride solubility is low and increases with NaF (LiF) concentration. ??

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.????

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 electrochemical study of YbCl3 in molten CsCl in the temperature range 973–1073 K. Transient electrochemical techniques have been used in order to investigate the reduction mechanism, transport parameters and thermodynamics properties of the reaction YbCl2+1/2Cl2=YbCl3. The results obtained show that the reduction reaction is reversible being controlled by the rate of the mass transfer. The diffusion coefficient of [YbCl6]3- complex ions was determined. The apparent standard electrode potential of the soluble–soluble redox system Yb3+/Yb2+ was obtained by cyclic voltammetry.

Аннотация: In the present investigation, a radically new and simple method of evaluation of the proton conductivity is proposed. This method is based on the conductivity measurement of ceramic materials depending on the oxygen partial pressure (pO2) at a gradual transition from the atmosphere of pure oxygen to one of wet hydrogen: O2 → O2 (H2O) → H2O (O2) → H2O → H2O (H2) → H2 (H2O). Experimental data of total conductivities for the solid electrolyte BaCe0.9Gd0.1O3–δ (BCG) have been fitted with modeling ones in accordance with the defect chemistry model at 600, 750 and 900 °C. Experimental and theoretical relationships correlate well with each other, demonstrating the success of the proposed model description. Analysis of dependences of the total conductivity as a function of pO2 with simultaneous change of pO2 and water partial pressure (pH2O) allows the estimation of the contribution of the partial conductivities (protonic, oxygen ionic, electronic) in the total one and the identification of the areas of purely ionic and purely protonic conductivity. Using the obtained data, some transport phenomena of proton-conducting materials, which were not previously interpreted, are discussed.

Аннотация: The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great interest in theoretical and experimental solid state electrochemistry. The present review aims at: (a) summarizing the evolution of new functional BaCeO3-based materials with respect to their properties, and properties’ optimization (importance of ceramics’ technology preparation, structural and thermodynamic stability of materials, enhanced ionic conductivity of electrolytes with low electronic contribution, thermal and chemical compatibility with other oxide components), and (b) examining the possibility of their application in various solid oxide electrochemical devices

Аннотация: The heat capacities of molten salts are very important for their practical use. Experimental investigation of this property is challenging because of the high temperatures involved and the corrosive nature of these materials. It is preferable to combine experimental investigations with empirical relationships, which allows for the evaluation of the heat capacity of molten salt mixtures. The isobaric molar heat capacities of all molten alkali and alkaline-earth halides were found to be constant for each group of salts. The value depends on the number of atoms in the salt, and the molar heat capacity per atom is constant for all molten halide salts with the exception of the lithium halides. The molar heat capacities of molten halides do not change when the anions are changed.

Аннотация: In the present work, composite materials of the type (1–x)SrTi0.5Fe0.5O3–δ–xCe0.8(Sm0.8Sr0.2)0.2O2–δ (with х = 0, 0.25, 0.5, 0.75 and 1) are obtained by the two step solid state technique. Their transport properties are investigated in terms of their usage as mixed ionic-electronic conducting (MIEC) membrane materials for hydrogen production. It is found that, in reducing conditions the composites are characterized by mixed conductivity, which level is controlled by the electrical properties of the prevailing phase. Moreover, at 900 °C and pO2 = 10−18 atm, total conductivity, ambipolar conductivity and oxygen permeability of composites dramatically grow (each of about 500%), when the fluorite component content x increases from 0 to 1. High-conducting and strengthened material 0.5SrTi0.5Fe0.5O3–δ–0.5Ce0.8(Sm0.8Sr0.2)0.2O2–δ is chosen for making tube shaped membranes using the tape rolling method, which are successfully applied for hydrogen production in laboratory scale. The hydrogen flux reached 0.176 ml cm−2 min−1 for x = 1, T = 900 °C and emf = 10 mV.
