摘要：

alpha-Al2O3 powder sample was synthesized at 550 degrees C via solution combustion synthesis (SCS) method using urea as an organic fuel. The sample was characterized by X-ray diffraction (XRD), Optical spectroscopy and X-ray photoelectron spectroscopy (XPS) without any further thermal treatment. XRD study reveals that the powder crystallized directly in the hexagons alpha-Al2O3 phase. A band gap of 5.7 eV was estimated using diffuse reflectance spectra. For surface investigation X-ray photo electron spectroscopy (XPS) was carried out. The XPS survey scan study of alpha-Al2O3 powder reveals that the sample is free from impurity. The core levels of Al-2s and O-1s are also reported.
