Background: Mg2TiO4 – based ceramics have proven their potentiality in the field of wireless
communication systems. In the past, Mg2TiO4 ceramics was considered a quite optical response
material in thin film form. Moreover, there is very few studies have been done whatever the proposed
work in the present study.
Objective: To prepare Mg2TiO4 nano-powders with the help of High Energy Ball Mill (HEBM) and
intend to investigate its effect on crystal structure, microstructure and on thermodynamic behavior of
Methods: Mg2TiO4 ceramics were synthesized using Mechanical alloying method from high- purity
oxides MgO and TiO2 (99.99%) of Sigma Aldrich (St. Louis, MO).
Results: From the experimental studies it is observed that the powder’s particle size decreases with an
increase of milling time. XRD analysis is carried out for phase confirmation of the mixed Mg2TiO4
powder. Further, the result also showed that there is structural changes occurred in the sample by high
energy ball milling process, milled at different times. The nanocrystalline nature Mg2TiO4 powder was
confirmed from microstructure taken by Field Emission Scanning Electron Microscopy (FE-SEM) and
Transmission Electron Microscopy (TEM). Further, differential thermal gravimetric analysis has been
carried out to investigate the thermal behavior of milled Mg2TiO4 -powder (35 hours).
Conclusion: In work, the effect of mechanical alloying on structural, microstructural and thermal properties
of nanocrystalline Mg2TiO4 powders has been investigated systematically. The effect of milling time
on particle size, crystal structure and the microstructure was studied using XRD, FE-SEM, TEM and
DSC/TGA analysis. The microstructural analysis (FE-SEM and TEM) reveals the nanocrystallinity nature
of MTO ceramics prepared by mechanical alloying method. The thermal decomposition behavior of
the milled powders was examined by a Thermo-Gravimetric Analyzer (TGA) in argon atmosphere.
