초록

Generally, Piezoelectric ceramics based lead-zirconate-titanate(PZT) system are well known to use in high power devices. In this pacer. Pb(Mn$\sub$1/3//Sb$\sub$2/3/)O$_3$(PMS) ceramics which have been shown to be adaptable for a high power usage is introduced. The stability of piezoelectric properties in PZ-PT-PMS solid solution system such as piezoelectric constants. electromechanical coupling coefficient and mechanical quality factor is discussed by the addition effect of CeO$_2$ as a additive. The CeO$_2$ ratio ranges from 0 to 2 wt%. The resonant and anti-resonant frequencies. mechanical quality factor, and force factor are also measured as a function of vibration velocity
