“…The Bi4Ti3012 ceramic was prepared by reaction sintering [5]. The mixture of Biz03 (Bismuth Institute, purity 99.9%) and Ti02 (GmbH Ventron, purity 99.8%) powders were homogenized for 24 h using a planetary ball mill.…”

The effect of oxidation and reduction atmospheres on the ferroelectric behavior of bismuth titanate was investigated. The effective surface density teff of free charges in s a m p l e s polarized by a p p l y i n g the electric field Ep = l MVm-l at the temperature of 1OO'C during 90 min was determined by comp e n s a t i o n voltage measurements. The thermally treated s a mples in oxidation atmospheres exhibit a significant decrease of r e j f while t h o s e treated in a reducing a t m o s p h e r e exhibit an increase a c c o m p a n i e d b y the improvement in stability of the electret charge. Such observations indicate that the formation a s well a s transformation of electret state of BbTi3012 ceramics may be related to the e n h a n c e m e n t and diminishing of oxygen vacancies. In all cases h o m o c h a r g e w i t h a time independent sign was obtained.1070-9878/95/ $3.00 @ 1995 IEEE

“…In comparison with the BIT ceramics starting from the powder through solid-state reaction, the sintering temperature of the present BIT sample was much lower. 17 The substitution of Nd for Bi in BNT seemed to retard the sintering and resulted in an increase in the sintering temperature. The optimized sintering temperature was 1050 • C for BNT02 and BNT05, and 1100 • C for BNT075, as shown in Fig.…”

“…109) Some authors have made studies on the reaction path during the formation of Bi4Ti3O12 from Bi2O3 and TiO2. Jovalekic et al 82) indirectly studied the reaction between bismuth and titanium oxides measuring the density of the mixture as a function of time and temperature. These authors concluded that the formation of Bi4Ti3O12 at temperatures over 825°C proceed by two reaction paths: the direct reaction between both oxides favoured by the melting of Bi2O3 at 825°C, and the formation of Bi-Ti-O compounds with different stoichiometry that melt at low temperatures to transform to the final Bi4Ti3O12.…”

Aurivillius oxides family has attracted great interest in the last years due to their promising electrical properties as high temperature piezoelectric materials. Piezoelectric materials that could operate in extreme conditions of use (elevated temperatures and hostile environments) could be of particular interest for different technological applications. Furthermore, increasing concerns for environmental issues have promoted the study of new lead-free piezoelectric materials. This article examines how the development of these materials has taken place from their discovery at the end of the 40's and the existing knowledge about their processing and properties.
