Soft piezoelectric ceramic composition and piezoelectric device using the same
摘要:
The soft piezoelectric ceramic composition is a soft piezoelectric ceramic composition sinterable at a reduced temperature with high piezoelectric parameters and is used in a piezoelectric device. Preferably the soft piezoelectric ceramic composition comprises: [(Pb1-m-nSrmBan)(1-y)Biy[](ZrxTi1-x)1-a-bNiaWb]O3+pCdO wherein m,n,x,y,a and b are molar ratio, p is wt % and are in ranges, repectively, 0.00≦m
