Abstract

Solid solutions with a perovskite structure are formed in the PbTiO₃-La(Me_2/3Nb_1/3)O₃ (Me:Mg,Zn) systems up to about 70 mol% of La(Me2, Nb. )0. Structural, dielectric, electromechanical and dilatational properties of the ceramics have been measured as functions of composition and temperature. The electromechanical coupling constants k and k at room temperature are 28% and 68%, respectively, in the composition1 near lo mol% of La(Mg_2/3Nb_1/3)O₃. The temperature coefficient of the radial mode resonance frequency less than I ppmK^-1 is obtained in the vicinity of 10 mol% of La(Me, Nbn,)0 with a small amount of MnO additive.
