Increasing demands on the quality of electronic ceramics requires a
well-controlled correlation between particle morphology and processing
conditions. Since mechanical activation is one of the methods
for modification of physico-chemical properties of dispersed systems,
in this study a correlation between the densification rate microstructure
evolution and fractal nature of mechanically activated
BaTiO3 has been analyzed. The high purity commercial BaTiO3
powder was mechanically activated in a planetary ball mill in a continual
regime for 60 and 120 minutes. Sintering under non isothermal
conditions was carried out up to 1380 °C. The shrinkage behaviour
of mechanically activated samples, has been analyzed by a sensitive dilatometer. Densification rate as a function of relative density
for different activation times has been calculated.Microstructure
investigations of sintered samples were carried out, using a scanning
electron microscope (SEM). The presented results enable... establishing
processing parameters that are indisensable for obtaining materials
with advanced properties.
