Abstract
The mechanical synthesis of nanocrystalline alpha-Al2O3 seeds from gam ma-Al2O3 to enhance the phase transformation kinetics of alumina is de scribed. The effect of milling rime on crystallite size, transformatio n temperature, transformation kinetics, and seed density are reported. it is shown that the transformation rate can be increased by several orders of magnitude by milling the material for short time periods.
