Effect of mill type on the size reduction and phase
Effect of mill type on the size reduction and phase

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.
