| ABSTRACT |
|
The piezoelectric properties and temperatureproperties of resonant frequency of the pseudoquaternary soild solution 0.075 Pb(Sb$frac{1}{2}$Nb$frac{1}{2}$)O3-0.025 Pb(Mn1/3Nb2/3)O3-xPbTiO3-(0.9-x) PbZrO3 were investigated. The composition range examined are 0.32 x 0.57. Specimens were prepared by the conventional mixed oxide technique, calcined at 850$^{circ}C$ for 1 hour and sintered at 1270$^{circ}C$ for 2 hours under PbO atmosphere. From the results of XRD, dielectric and piezoelectric properties, it is supposed that the MPB composition between tetragonal and rhombohedral ferroelectric perovskite exists in 0.42$^{circ}C$ was considered at the nearby MPB. |
