چکیده انگلیسی
Li3InBr6 â xClx was synthesized and the substitution effect on conductivity was investigated. Li3InBr6 â xClx was single phase at all compositions. The volume of crystal lattice was decreased with Cl content and the rate of the decrease changed at x = 3. The conductivity of Li3InBr6 â xClx had a maximum in Li3InBr3Cl3 and its value was 1.2 Ã 10â4 Scmâ 1 at 300 K. The activation energy of the conduction was at the minimum around x = 3 and its value was 20 kJ molâ 1. Phase transition temperature was lowered to be 285 K and the high conduction phase was stabilized by substitution Br with Cl. 7Li NMR spectra in Li3InBr3Cl3 was sharp and it was confirmed that the diffusion of Li ion was fast at room temperature.
