Abstract

Nanocrystalline alumina powder was produced from calcinations of Al13-oxalate precipitates at 1100 1C. A nearly normal distribution
of agglomerated alumina powder was obtained with an average particle size of about 1 mm. XRD measurement confirmed that the
alumina produced was of high purity and crystalline a-phase. Microstructural features of both the precipitates and alumina obtained
were studied using the small angle neutron scattering (SANS) technique. SANS examinations show the formation of microstructures in
the alumina powder of mass fractals type with dimension of 2.8 indicative of low intra-granular porosity.
