Abstract
Submicronic MgAl2O4 powders have been synthesized by decomposition of the double alkoxide Mg[Al(O-secBu)4]2 in supercritical ethanol. The influence was studied of various experimental parameters (reaction time and temperature, reactional medium concentration and density) on the main characteristics of the obtained materials. Particularly, sample crystallinity and chemical composition, particle size distribution and mean diameter were investigated by X-ray diffraction, IR spectroscopy, laser scattering and electronic microscopy.
