Abstract: The Sr2TiO4 samples were synthesized by mechanical activation (MA) from a mixture of SrCO3 and TiO2 precursors followed by calcination at 900 and 1100°C. The accumulation of internal energy stresses in the mechanical mixture of precursors was controlled by varying the mechanical activation time (10, 20 and 25 minutes) through the use of mills of different power. Powder mixtures of precursors as-blend, after MA, and after calcinations were studied using XRD, FTIR, thermal analysis, and SBET methods. The energy impact in Sr2TiO4 synthesis is more pronounced at calcination temperature of 900 °C, the increase in the energy load at a temperature of 1100 °C is levelled out, due to the formation of practically single-phase Sr2TiO4.
