    XRD and TEM studies confirm that the planetaryball mill causesphase transformation to the less desired α-Alumina resulting in a notabledecreasein surface area from 136.6 m 2 /g to 82.5 m 2 /g as measured by the BET method. This is consistent with the large shear stresses under high shear rates prevailing in the planetaryball millwhen compared to the other mill types.
