The influence of heating rate on solid-phase interaction in Li[2]CO[3]-Fe[2]O[3] reaction mixture was investigated by thermal analysis method. The powder mixture components were in the ratio corresponding to LiFe[5]O[8] ferrite. The ferrite synthesis was performed by thermal heating of mixture reagents in thermal analyzer up to 800 °С in air at various heating rates in the ranges (5-50) °С/min. The results showed that the heating rate affects the solid-phase interaction in Li[2]CO[3] - Fe[2]O[3] reaction mixture. The reaction phase formation is accompanied by heat endothermic effect, which was observed in the DSC curve in the form of a complex broad peak. For all samples, this complex peaks were decomposed into simpler peaks, and thereby, the enthalpies of the individual phase transitions were determined. It was shown that the heating rate affects the values of enthalpy and temperatures of heat endothermic effects, so that the high heating rate shifts the proceeding of reaction to higher temperatures.
