Abstract

The application of the ultrasonic nozzle has been extended because it can atomize liquid material. In this study, the characteristics of the ultrasonic nozzle and ceramic oscillator were investigated. The oscillator for the ultrasonic nozzle is made of piezoelectric ceramic of Pb[(Sb _1/2Nb_1/2)_0.035, (Mn_1/3/Nb _2/3)_0.065, (Zr_xTi_1-x) _0.90O₃ The electromechanical coupling factor (k _p) and mechanical quality factor (Q_m) were 0.555 and 1,214, respectively, when the Zr/Ti ratio was 49/51. Moreover, this oscillator will have temperature stability because its curie temperature is 322. The driving current of the ultrasonic nozzle was 80 mA, when the driving time was 10 min. Also, the surface temperature of the ceramic oscillator was 80 at a driving time of 10 min. We discovered that the ultrasonic nozzle will be subjected to stable driving after 10min.
