The redox chemistry of niobium(V) fluoro and oxofluoro complexes in LiF-NaF-KF melts
The electrochemical behavior of niobium(V) fluoro and oxofluoro complexes in eutectic LiF-NaF-KF (FLINAK) melts at 700°C has been studied by cyclic voltammetry. The fluoro complexes NbF, introduced into the melt by the addition of K2NbF7, can be reduced to niobium metal in two reversible steps involving one and four electrons, respectively. At 700°C the diffusion constants of the fluoro niobate...
متن کاملEXCESS HEAT IN MOLTEN SALTS OF (LiCl − KCl) + (LiD + LiF) AT THE TITANIUM ANODE DURING ELECTROLYSIS
The electrochemical cell and a technique for precision calorimetric measurements has been developed. Experiments with molten salts containing lithium deuteride were carried out. Calorimetric measurements made on the titanium anode during experiments. Measurements were made in an inert atmosphere of helium and in an atmosphere of deuterium at various density of an electrolysis current. Excess he...
متن کاملAb initio Hartree - Fock Born effective charges of LiH , LiF , LiCl , NaF , and NaCl
We use the Berry-phase-based theory of macroscopic polarization of dielectric crystals formulated in terms of Wannier functions, and state-of-the-art Gaussian basis functions, to obtain benchmark ab initio Hartree-Fock values of the Born effective charges of ionic compounds LiH, LiF, LiCl, NaF, and NaCl. We find excellent agreement with the experimental values for all the compounds except LiCl ...
متن کاملCOMPACT TUNABLE LiF COLOR CENTER LASER SYSTEM
The laser utilizing LiF crystal with F2 color centers (CC) is an efficient and reliable source of tunable radiation which covers a broad near IR spectral region that is very important for scientific applications and allows using CC lasers for spectroscopic investigations of rare earth doped laser materials [1]. The CW operation of LiF:F2 CC laser is complicated due to short lifetime of F2 CC (5...
متن کاملAlkali and Halogen Chemistry in Volcanic Gases on Io
We use chemical equilibrium calculations to model the speciation of alkalis and halogens in volcanic gases emitted on Io. The calculations cover wide temperature (500-2000 K) and pressure (10 to 10 bars) ranges, which overlap the nominal conditions at Pele (T = 1760 K, P = 0.01 bars). About 230 compounds of 11 elements (O, S, Li, Na, K, Rb, Cs, F, Cl, Br, I) are considered. The elemental abunda...
