The properties of doped BaTiO3 ceramics prepared from mechanically activated precursors (BaCO3, TiO2, PbO), dopant (Sb) and admixtures (SiO2, Al2O3) were investigated. Mechanical activation of the mixture 1.00 BaCO3 + 1.15 TiO2 + 0.10 PbO brings about an increase in its specific surface and partial amorphization of BaCO3; Ba, O and C occur in the surface of this mixture in at least two chemically different states. BaTiO3 obtained from the above mentioned mechanically activated precursors by high-temperature solid-state synthesis at 1100 degrees C consists of homogeneous particles with a narrow particle size distribution.
