A one-step synthesis and consolidation of nanostructured Mg 0.3 Al 1.4 Ti 1.3 O 5 was achieved by high-frequency induction heating, using the stoichometric mixture of MgO, Al 2 O 3 and TiO 2 powders. Before sintering, the powder mixture was high-energy ball milled for 10 h. From the milled powder mixture, a highly dense nanostructured Mg 0.3 Al 1.4 Ti 1.3 O 5 compound could be obtained within one minute, under the simultaneous application of 80 MPa pressure and an induced current. The advantage of this process is that it allows an instant densification to the near theoretical density, while sustaining the nanosized microstructure of raw powders. The sintering behavior, microstructure and mechanical properties of Mg 0.3 Al 1.4 Ti 1.3 O 5 compound were evaluated.
