چکیده انگلیسی
Lead-free (1 â x)wt.% (Ba0.85Ca0.15)(Zr0.10Ti0.90)O3 â x wt.% (Ba(Cu0.5W0.5)O3 (BCZT â x wt.% BCW) piezoelectric ceramics were prepared by solid-state reaction. The phase structure of the ceramics showed that the orthorhombic-tetragonal phase boundary was identified in the range of 1.2 â¤Â x â¤Â 1.6 wt.%. The dense microstructure and optimal electrical properties of the ceramics were obtained at x = 1.2 wt.%. Fatigue behavior of the ceramics was also investigated as a function of temperature and keeping time, where the BCZT â 1.2 wt.% BCW materials were found to possess improved fatigue characteristic. In addition, the sound pressure level (SPL) of 16.0 mm length Ã 16.0 mm width Ã 0.1 mm piezoelectric loudspeakers using lead-free BCZT ceramics with 1.2 wt.% BCW content at drive voltage of 10-20 V was more than 80 dB at frequency of 2.2-20.0 kHz. These results indicated that the 98.8 wt.% BCZT â 1.2 wt.% BCW ceramics was potential for piezoelectric loudspeaker applications.
