Abstract :A Solution Combustion method used to synthesis nano crystalline γ-Alumina powders by reaction between aluminium nitrate as oxidizer and a mixture of urea and camphor fuel as reducer. stoichiometric fuel is Urea and camphor was added as excess fuel to alter the exothermicity of redox reaction between aluminium nitrate and urea. The ratio of urea to camphor had been optimized to obtain single phase gamma alumina. The variation of adiabatic flame temperature was calculated theoretically for different urea/camphor mixture ratios according to thermodynamic concept and correlated with the observed flame temperatures. These powders were characterized by XRD, SEM, An interpretation based on maximum combustion temperature and the amount of gases produced during reaction for various urea to camphor ratio composition had been proposed for the nature of combustion and its correlation with the characteristics of as synthesized Powder.
