| Riassunto: | Title screen In 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.
