Lead calcium titanate piezoelectric ceramic element |
| 摘要 |
An improved lead calcium titanate piezoelectric sintered body is produced by sintering in air at 1000 DEG C.-1200 DEG C. a calcined mixture of oxides or oxide compounds in amounts adapted to form a composition of the formula Pb1-xCaxTi1-y(Co1/2W1/2)yO3+0.005-0.02(A) where A is at least one of MnO, MnO2, NiO and Nb2O3, wherein x=0.3-0.4 and 0.04<y</=0.06.
