Abstract:
A process for producing metastable nanocrystalline alpha-alumina (α-Al 2 O 3 ) having particle sizes smaller than 12 nm. Starting crystallites of α-Al 2 O 3  having a particle size larger than 12 nm, typically on the order of about 50 nm, are ball-milled at low temperatures to produce a nanocrystalline α-Al 2 O 3  powder having a particle size of less than 12 nm, i.e., below the theoretical room temperature thermodynamic size limit at which α-Al 2 O 3  changes phase to γ-Al 2 O 3 , wherein the powder remains in the α-Al 2 O 3  phase at all times.

Claim (Index 2):
The process according to  claim 1 , wherein the ball-milling media is WC-Co.
