Size-controlled synthesis of alumina nanoparticles from aluminum alkoxides

摘要: Abstract Aluminum oxide nanoparticles were prepared by the hydrolysis of aluminum alkoxides followed calcinations, in presence surface stabilizing agents, such as Na(AOT) molecules. The size alumina precursors (bohemite) was 20–30 nm, yielding particles with an average 80 nm after calcinations at 1200 °C. shape α-alumina mainly spherical and high temperature inhibited formation hexagonal crystals. introduction during appropriate processing step, had effect controlling particles, degree aggregation shapes.
