α-Al2O3 nanoflakes with od dispersion and uniform size were controllably synthesized using a self-burning method under similar conditions and with aluminum nitrate and glycin as raw materials. Product structure was studied by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, etc. Thermodynamic properties of the precursor were studied using thermogravimetry-differential thermal analysis (TG-DTA). The effects of different morphologies and sizes of α-Al2O3 nanomaterials on their polishing property were investigated for the first time. Results of the polishing study indicate that the small size nanoflakes with a high purity quotient have the best polishing property compared to other α-Al2O3 materials. This study is expected to have potential value for the industrial production and practical application of these α-Al2O3 nanomaterials in the polishing field.
