Abstract

Solid solutions in the PbTi03-La(Zn2/3Nbi/3)03 system are formed with a perovskite structure up to 70 mol % of La(Zn2/3Nb1/3)03 content. Dielectric and electromechanical properties of the ceramics have been measured as functions of temperature. The ferroelectric Curie temperature decreases linearly with increasing La(Zn2/3Nbi3)03 content. The planar coupling factor kp at room temperature shows a maximum of 23% in the composition with 13 mol% of La(Zn2/3Nbi/3)03. A minimum of the temperature coefficient of the planar resonance frequency \Af/fAT\ at room temperature (3.7 x 10“5 K-1) is obtained at 10.5 mol% of La(Zn2/3Nb1/3)03. By adding a small amount of Mn02 to the ceramics, the order of magnitude of \Af/fAT\ can be reduced to 10“6 K-1.
