Abstract: Based on thelow temperaturecombustion synthesisof α Al2 O3 from aluminum nitrate,the effectsofthe additives on the formation and particle properties of α Al2 O3 werestudied by XRDand SEM,theinitialstudy on the manometer α Al2 O3 synthesisby LCSwas done, α Al2 O3 withtheparticlesize50 ~80 NM wasgot under properconditions.

Key words: low temperature combustion synthesis, nanometer α Al2 O3 , additive, dextrin
