The wear performances of fine grain alumina ball adding diopside as fluxing agent are reported for the first time in this paper. The ball (average grain size 3μm) exhibits excellent toughness and low wear rates. Ploughing grooves and traces of micro-cutting occur at the place with no pore. And the wear process is mainly caused by plastic deformation mechanism. Yet, the ordinary alumina balls (average grain size 6 and 15μm) are brittle and the wear rates are high. The intergranular and transgranular dropping pits occur, and the wear process is mainly caused by brittle fracture mechanism.
