The effect of rapid thermal annealing and conventional furnace annealing on the crystallization of SrBi 2 Ta 2 O 9 is modeled using an Arrhenius-type equation. Based on previous experimental results several authors have suspected that different reaction mechanisms occur depending of the heating rate employed in these two treatment methods. Oppositely, the results here presented...
A new procedure based on an ethanolic solution of the appropriate cations to obtain SrBi 2 Ta 2 O 9 (SBT) thin films is described, reducing the necessity of toxic organicals. According to X-ray diffraction analysis the desired SBT crystalline phase is obtained after heat treatment at 720 °C, in air, for 20 min. The ferroelectric properties of the obtained thin film include...
