摘要：

During the synthesis by mechanochemical activation of the Aurivillius-like oxides the stabilization of oxygen deficient fluorite-type phases, never isolated before now, has been carried out. The corresponding Aurivillius oxides have been obtained about 350 degrees C below the necessary temperature for the synthesis by solid state reaction. Impedance spectroscopy measurements of Bi3NbTiO9 fluorite-type phase have shown an increase of the conductivity value of the Aurivillius phase, arising to about 10(-3) ohm(-1).cm(-1) at 450 degrees C.
