| titleOfInvention | Piezoelectric composition |
| abstract | (57) [Summary] [Purpose] The Curie temperature is high, the reduction rate of the electromechanical coupling coefficient up to near the Curie temperature and the mechanical quality factor Qm are small, and the heat resistance and mechanical strength are excellent. A large piezoelectric ceramic composition is obtained. [Constitution] 0.1% of Pb atom of lead zirconate titanate The 8 mol% substituted with at least one Ba, Sr and Ca, 0 this Sb, in terms of at least one of Nb and Ta to Sb 2 O 3, Nb 2 O 5, Ta 2 O 5 , respectively .5 To 1.9 wt% and at least one of Cr, Fe, and Mn is added as 0.1 to 0.8 wt% in terms of Cr 2 O 3 , Fe 2 O 3 , and MnO 2 , respectively. In addition, Si, At least one of Ge is added in an amount of 0.001 to 0.25 wt% in terms of SiO 2 and GeO 2 . |
