Synthesis, Microstructural and Thermal analysis of inverse spinel compound Mg2TiO4

Abstract

In the present work, the influence of mechanical activation on Mg2TiO4 has been studied. High-energy wet ball-mill and post-anneal processing were applied to synthesize Mg2TiO4 single phase crystalline material. The mixture of Mg(NO3)2.6H2O and TiO2 were mechanically activated for 10, 15, 24 and 48 hours in a planetary ball mill and sintered at 1300 ºC for 72 hours. Phase composition, morphological changes and thermal stability of the sample have been analyzed. The thermal analysis of Magnesium Ortho Titanate reveals the exothermic reaction to the abrupt change in two steps.
