In this study, α-alümina structures are successfully prepared via hydrothermal synthesis supported with PEG-400. The effect of the PEG-400 as structure directing agent on the particle size is investigated. The structural characterization of the prepared powders is carried out using XRD, Raman and FTIR techniques. TGA analysis technique is used for the investigation of the thermal properties of the powders. Morphological properties are investigated using SEM technique. Obtained results show that comparing with the experiment without the use of the structure directing agent, pure α-Al2O3 was obtained in smaller size.
