Abstract
The changes of physico-chemical properties of mechanochemically pretreated (BaCO3+TiO2+PbO) powders were investigated. The values of apparent activati on energy of BaTiO3 formation calculated by the Freeman and Carroll method decrease with milling time. The changes of precursors density may be interp reted as a consequence of mechanochemical reactions during milling.
