Abstract

In this paper, for the application of ultrasonic cleaners for cleaning dentures and transparent braces, Pb(Mn1/3Nb2/3)O3-Pb(Ni1/3 Nb2/3)O3-Pb(Zr,Ti)O3 [PMN-PNN-PZT] system ceramics were manufactured and their dielectric and piezoelectric properties were investigated. Overall the best properties suitable for the device applications such as ultrasonic cleaner were obtained from the ceramics sintered at 920℃: bulk density of 7.8 g/cm3, the dielectric constant (εr) of 1,689, piezoelectric charge constant (d33) of 433 pC/N, planar electromechanical coupling factor (kp) of 0.64, mechanical quality factor (Qm) of 835, S11E of 13.37 (10-12 N/m2), and Curie temperature of 315℃ By using the physical properties of this composition, the ultrasonic cleaner was designed and simulated using the commercial ATILA software. For the three-layered ceramics with the dimension of 25 mm × 25 mm × 2.5mm, an excellent displacement of 8.998 10-3 m) and the sound pressure of 147.68 dB were recorded.
