Abstract
Alumina particles with plate-like shape were prepared successfully by a wet chemical processes with nano-size aluminum additive. The seed-effect of nano-size aluminum and its effect on the final α-Al 2O 3 particle size and shape were investigated. TEM, XRD, XPS, Zeta potential and DSC/TG were used to observe the microstructure of the α-Al 2O 3 particle and analysis this wet chemical processes. It was found that aluminum additive not only helps to produce the nano-size plate-like α-Al 2O 3 particles effectively but also reduces the formation temperature of α-Al 2O 3.
