| 英文摘要 | We prepared 3 kinds of Li+-doped BaTiO3 ceramics by the solid-state reaction method: (i) (Ba1-xLix)TiO3-x/2 having A-site Li+, (ii) Ba(Ti1-xLix)O3-3x/2 having B-site Li+, and (iii) x/2 Li2CO3+BaTiO3 mixed one, for which we investigated the stable site of Li. The density of all prepared ceramics is above 95%. The results show that the lattice structure, the grain size, and the electric properties of Li+-doped BaTiO3 ceramics are dependent on Li+ site. According to the increase in Li content, the cell volume of Ba1-xLixTiO3-x/2 decreases, but that of BaTi1-xLixO3-3x/2 increases. That of x/2Li(2)CO(3)+BaTiO3 decreases by the small addition of Li, but increases by the large addition of Li. All Li+-doped ceramics show antiferroelectric-like double hysteresis loops. The shape of loops and the dielectric properties are also dependent on the Li site. We suggest that the role of oxygen vacancy accompanied by the Li-doping is important. By comparison with the results of 3 type ceramics, it is concluded that at x/2Li(2)CO(3)+BaTiO3 ceramics, the Li+ prefers to favorably substitute Ba2+ at A site for the low concentration of Li but its location was changed to Ti4+ site for the high concentration of Li. |
