Preparation of PLZT Ceramics via Mechanical Alloying

Abstract

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
