 Abstract    The structural and dynamic properties of molten lithium iodide are investigated at two pressures (334 MPa at 784 K and 1054 MPa at 915 K), using molecular dynamics simulations with Born-Mayer-Huggins type pair potentials. On increasing the pressure, the local packing of the ions changes from tetrahedral to octahedral, the self-exchange velocity in the coordination shells decreases by a factor of 0.031, Du by a factor of 0.033 and D, by a factor of 0.021.

 Title    Zur ionischen Leitfähigkeit gemischter Lithiumiodid-Verbindungen The Ionic Conductivity of Mixed Lithium Iodide Samples  
 Abstract    The ionic conductivity of some polycrystalline samples of the general formula Lil • yXl (y = 1/4 or 1/10) X = Rb+, NH4+, N(CH3)4+, NEt4+) is measured. These mixtures generally exhibit higher activation energies for ionic movement than pure lithium iodide. At temperatures above 50 °C, the overall conductivity is higher them that of pure lithium iodide.

 Title    X-ray Diffraction Studies on Supercooled Aqueous Lithium Bromide and Lithium Iodide Solutions  
 Abstract    X-ray diffraction measurements were performed on liquid LiBr • 5H 2 0 and Lil • 5H 2 0 at tem-peratures from —30 to 25 °C. The total radial distribution functions did show that on supercooling the hydration shell of the halide ions becomes more structured, while that of the lithium ions becomes distorted. The larger the halide ion, the stronger becomes the water-water interaction around halide ions with lowering temperature. However, the distance between the water molecules in the hydration shells of the halide ions depends little on their size. On the basis of the present results, together with those of our previous investigation on LiCl • 5H 2 0 at temperatures from — 135 to 100°C, the effects of temperature and the size of the halide ions on the structure of the solution are discussed.
