330 _aIn this work, the effect of ball milling of Li2CO3 and Fe2O3 reagents on the Li0.5Fe2.5O4 ferrite formation was studied by thermogravimetric and differential scanning calorimetric measurements using non-isothermal heating and cooling modes. In the latter case, the analysis was carried out with a magnetic field applied in order to estimate the Curie temperature of the synthesized ferrite. The mechanical milling of both individual Li2CO3/Fe2O3 reagents and their mixture was performed with an AGO-2C planetary mill using steel vials and balls. Samples with different bulk densities, which were compacted from non-milled and milled powders by pressing with different compaction pressures, were investigated. The results showed that the mechanical milling of powder reagents separately does not cause a significant change in the reactivity of the ferrite system. Only milling of the Li2CO3/Fe2O3 mixture makes it possible not only to increase the reactivity of powders, but also to exclude additional compaction of samples before synthesis.
