| Zusammenfassung: | The crystal structure and the ionic and partial electronic conductivity of the LixLayMzTi1-xO3 (M = Ni, V, Cu, 0.25 < x/y < 1.44 and z = 0.0,0.,0.2) and of the LixLayCozTi1-zO3 (0.19 < or = x < or = 0.55; 0.55 < or = y < or = 0.8 and z = 0.0,0.1,0.30) systems, with perovskite-related structure, have been studied. Partial substitution (5,10 and 30%) of Ti4+ ions by slightly larger Co2+ and Ni2+ ions was found to stabilise the cubic perovskite structure (S.G. Pm3m; Co, a = 3.88450(6) A and Ni, a = 3.8849(1) A), with one exception (Li0.19La0.67Co0.1Ti0.9O3) giving a tetragonal symmetry plus supercell reflections. |
