In this research, α-Al2 O3 nanopowder was successfully synthesized via a new wet chemistry (liquid phase reaction) method. Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used for the characterization of the synthesized nanopowder. The FTIR and XRD results showed that α-alumina nanopowder was synthesized from ammonium dowsonite powder after the calcination at 1150 °C for 1 h. Also, SEM micrographs showed that the final nanoparticles have aggregated structures in 50–100 nm range.
