Abstract
During the synthesis by mechanochemical activation of the Aurivillius-like oxides the stabilization of oxygen deficient fluorite-type phases, never is olated before now, has been carried out. The corresponding Aurivillius oxid es have been obtained about 350 degrees C below the necessary temperature f or the synthesis by solid state reaction. Impedance spectroscopy measuremen ts of Bi3NbTiO9 fluorite-type phase have shown an increase of the conductiv ity value of the Aurivillius phase, arising to about 10(-3) ohm(-1).cm(-1) at 450 degrees C.
