Effects of High Energy Ball Milling on the Piezoelectric Properties of Lead-free (K0.44Na0.52)(Nb0.86Ta0.10)-0.04LiSbO3 Ceramics

다국어 초록 (Multilingual Abstract)

Lead-free (K0.44Na0.52)(Nb0.86Ta0.10)-0.04LiSbO3 piezoelectric ceramics have been synthesized by conventional sintering process and
then investigated on the sintering and piezoelectric properties by high energy ball milling (HEBM) treatment. The powders milled for
different time are characterized by XRD, FE-SEM. The powders are pressed into a pellet and sintered. It is found that the piezoelectric
properties of sintered specimens are strongly dependent on the milling time. The piezoelectric properties are enhanced by high energy
ball milling treatment. The planer electromechanical coupling factor (kp) and piezoelectric constant (d33) of a specimen sintered at
1050oC are 0.44 and 267 pC/N, respectively.
