High h− ionic conductivity in barium hydride
WebNd 2 LiHO 3, which has a space group Immm, in which ∼5% of the O sites (2d) are occupied instead by H, had the highest conductivity at 280 °C of 2.2 × 10 −5 S cm −1. The possibility of long-distance H − diffusion in Ln 2 LiHO 3 was computationally investigated. Web1 de mai. de 1994 · Barium-nitrade-hydride is one of the few documented H − -ionic conductors. It crystallises in the α-NaFeO 2 -structure (space group R 3 m) with distorted Ba-octahedra centred alternately by H − and N 3−. Neutron diffraction shows that the hydrogen ions are distributed independent of temperature over lattice sites: 85% on (3a) …
