| 摘要 |
A piezoelectric material and a method of producing a piezoelectric material which has a low temperature coefficient of resonant frequency, a low hysteresis, a high mechanical Q, and is suitable for fabricating into mechanical filters. The material is a compound of the general formula Pb(Zr,Ti)O3 containing Bi substituting for 2 to 15 atomic percent of the Pb and further containing Mn, Zn, and Ni substituting for up to 4 atomic percent of the Zr and Ti.
