摘要：

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