- Nanopowders of MgO and TiO2 were made by high energy ball milling. The rapid synthesis and sintering of nanostuctured MgTiO3 compound was investigated by the pulsed current activated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. Highly dense nanostructured MgTiO3 compound was produced with simultaneous application of 80 MPa pressure and pulsed current of 2800 A within 2 min. The sintering behavior, gain size and mechanical properties of MgTiO3 compound was investigated.
