Abstract
Fine particles of aluminum oxide (amorphous, alpha, gamma and theta) h ave been synthesized by spray pyrolysis as a function of both in situ and annealing temperatures and nature of precursors used in the prepar ation method. A scanning electron micrograph study shows as-received m aterials constituted by filled spherical particles, the ulterior annea ling leading to the formation of small crystallites on the precursor s pheres.
