Abstract:


Methods: Mg2TiO4 nanocrystalline powders have been synthesized by mechanical synthesis method using high-energy planetary ball-milling for different milling times (5, 20, 30 and 35 hours). The impact of mechanical activation on structural, microstructural and thermal properties of nanocrystalline Mg2TiO4 ceramics is investigated.

Results: 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. The impact of mechanical activation on the microstructure is evaluated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), to confirm the nanocrystalline nature of the milled Mg2TiO4 powder.

Conclusion: Further, differential thermal gravimetric analysis has been carried out to investigate the thermal behavior of milled Mg2TiO4-powder (here, 35hours).
