| Abstract: | The preparation technology of modified PbTiO 3 piezoelectric ceramics with large anisotropy is investigated by experiment, which is substituted by (Mn 1/3 Sb 2/3 ) 4+ in the B site. Through detailed investigating the effect of technological conditions on properties of this modified PbTiO 3 ceramics, the advantageous technological parameters are obtained. Under these conditions, the ceramics, possessing high piezoelectric activities, large piezoelectric anisotropy as well as low dielectric constant, and low mechanical quality factors, has great practical prospects in the developing of many ultrasonic transducers. |
