摘要: Solid solutions (1− x) NBT–xBF, between rhombohedral compounds Na0. 5Bi0. 5TiO3 (NBT) and BiFeO3 (BF) were studied and a continuous R3c solid solution was evidenced. Lattice parameters and rhombohedral distortion evolution with BF content were studied. The “a” pseudo-cubic parameter (ap) increases linearly with BF rate, as the “α” pseudo-cubic one (αp) presents a more complex behaviour. The study of the dielectric properties evidenced two different ranges, with a limit composition around 50% of BF. TEM studies of the …
