Reduction in grain size of doped PZT ceramics for miniature sensors and actuators by ball milling technique
Piezoelectric ceramics Pb(Zr0.52Ti0.48)O-3 (PZT) doped with Bi4Ti3O12 were investigated via ball-milling technique. It was found that the doped PZT ceramics not only had sub-micron grain size without appreciable degradation to their piezoelectric properties, but also enhanced fracture toughness value. Thus, it is feasible to produce fine grain miniature sensors and actuators by ball milling technique.
