Abstract
A technological method has been developed for the manufacture of multicomponent ferroelectric piezoelectric materials based on lead titanate, including those modified by oxides of rare-earth elements, of the Pb(Ti, Zr)O3 binary system, and alkali metal niobates. The method is considered step by step on the example of the composition Pb0.88Nd0.1Ti0.92Mn0.02In0.06O3 and consists in additional heat treatment of the synthesized product at a temperature corresponding to the termination of the change in the unit cell parameters. It is shown that the materials obtained by using the proposed method have improved characteristics in comparison with similar ones realized in materials manufactured by the traditional method. The developed materials are promising for the creation of high-frequency electroacoustic transducers, ultrasonic flaw detectors, and medical diagnostic devices.
