Dielectric, Piezoelectric and Pyroelectric Properties of Ceramic Solid Solutions Based on PMN-PT and PZT

Using the method of two-stage solid-phase synthesis, involving mechanical activation of the synthesized powders and subsequent sintering using traditional ceramic technology, ferroelectric multicomponent solid solutions based on the PZT and PMN-PT systems were produced, characterized by fairly high Curie temperatures and pyroelectric coefficients, high coefficients of pyroelectric sensitivity and resistance to vibration interference, which makes it possible to classify them as to pyroelectric materials, are promising for use as working elements of sensors for pyroelectric receivers of radiant (thermal) energy.
