Synthesis and characterization of sub-micron alumina by combustion of aluminum complexes with acetylacetone and salicylaldehyde

Sub-micron. alumina powders were synthesized by the combustion method using aluminum complexes of acetylacetone and salcylaldehyde. in this study, the powders were synthesized by solution combustion without the fuel. the phase transition and particle characteristics of the al2o3 were determined by examining the crystalline structure before and after the heat treatment were investigated by ft-ir and fesem technique.
