Barium titanate (BaTiO3) has been used in many applications such as multilayer
capacitors, piezoelectric ceramics, transducer devices, PTC resistor and has become one of
the most important ferroelectric ceramics. It is used extensively in ceramic capacitors, due to
its high dielectric constant and low loss characteristics.
Barium titanate was prepared by two methods, polymeric organometallic precursors
process and mechanochemicaly. X ray and SEM were used for caracterization of powders
and sintered samples. In both ways of synthesis the formation of cubic phase is obtained. It
can be observed that in the case of Pechini process BaTiO3 powder is well crystallized but in
the case of mechanochemically process, significant amount of amorphous phase was detected.
The sintered samples at 1300'C for 2h, prepared by Pechini process, shows the formation of
tetragonal phase. The morphology of the powders consists of particles and its agglomerates,
their dimensions depend of the synthe...sis method. The powder prepared mechanochemicaly
posses more agglomerates. The particles are bigger and with irregular shape. Average particle
size is about 100 nm and 250 nm for Pechini and mechanochemical process, respectively. In
sintered samples, prepared by Pechini process, at 1300oC for 2h is observed two types of
domain configuration. The wall thickness ranges from 0.08 pm up to 0.14 pm and from 0.14
Fm up to 0.17 pm for 90' and 180'domains respectably. The domain width is around 0.20
micron for both types of domains.
