Abstract:
The stoichiometric LSBN-SBT ceramic system was obtained for different concentrations of Titanium ions, where the Nb5+ was substituted by Ti4+ according to the following expression Sr0.255La0.03Ba0.7Nb2-yTiyO6-y/2. Oxygen vacancies are thus created which, together with the vacancies in the A sites of the TTB material structure, play an important role in their phase transition and dielectric properties, due to the crucial role that the occupancy of the crystallographic sites plays in such kind of structures.
