A Novel Method for Synthesis of Al2O3 Using Urea at Elevated Temperature

Moamen S. Refat and Abdel Majid A. Adam

The Al2O3 was synthesized by a novel reactions of urea with Al(NO3)3 or Al2(SO4)3, in an aqueous media at ~ 90o C. The infrared spectra and microanalysis, CHN, of the solid products indicated the absence of the bands of urea, but appearing the characteristic bands of oxide. A general mechanism describing the formation of oxides and decomposition of urea are suggested.
