This study investigates the physico-chemical properties of mechanochemically pretreated powders consisting of BaCO3, TiO2, and PbO, which serve as precursors for the synthesis of barium titanate (BaTiO3). The primary objective is to analyze the thermal properties and density changes of these powders as affected by milling time. Employing the Freeman and Carroll method, the apparent activation energy for BaTiO3 formation is calculated, revealing a decrease with increased milling duration. The changes observed in the density of the precursors are attributed to mechanochemical reactions during the milling process. Experimentation includes the use of chemically pure substances, with specific milling conditions applied to achieve desired material properties. Results indicate a significant impact of mechanochemical pretreatment on the thermal characteristics of the precursor powders, which could influence the solid-phase product in terms of its performance in electronic applications. This exploration into the mechanochemical processing of precursor materials highlights its potential to enhance the synthesis quality of doped BaTiO3 ceramics.
