Abstract: The preparation of PLZT ceramics $via$ mechanical alloying was studied. The result shows that PLZT powders can
be synthesized via high energy ball milling for 5h with nano-TiO2 powders, while only very weak PLZT peak can be found from the XRD pattern of the oxide
mixtures milled for 30 h without nano-TiO2 powders. So nano TiO2 particles are very important to synthesize PLZT powders via mechanical alloying. High density
PLZT ceramics were obtained by using the ball milled powders by sintering from 1000 to 1200℃. Piezoelectric and ferroelectric measurement results of the sintered PLZT ceramics were
comparable with the values reported in the literature for the same composition.

Key words: nano, mechanical alloying, high energy ball milling, PLZT ceramics
