Abstract
Nanopowders of Al2O3 and TiO2 were made by high energy ball milling. The rapid synthesis and sintering of a nanostuctured Al2TiO5 compound were investigated by the high-frequency induction heated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. A highly dense nanostructured Al2TiO5 compound was produced with simultaneous application of 80 MPa pressure and an induced current of total output power capacity (15 kW) within 3 minutes. The grain sizes of Al2TiO5 sintered at 1250 οC and the hadnesses were investigated.
