Polarization and switching processes in multicomponent piezoceramic based on PZT with a highly diffuse phase transition

摘要

It is known that in a multicomponent piezoceramics with a certain ratio of the components of the solid solution and modifying impurities, the phase transition from the ferroelectric phase to the paraelectric phase occurs in several stages. The temperature interval of structural and polarization changes can reach hundreds of degrees. In the present work polarization switching processes and properties of a piezoceramic material based on PZT o0: 36PbTiO3 0: 33PbZrO3 PboMgZnTHORN 1= 3 Nb2= 3O3 BaTiO3 SrZrO3 THORN studied. studied.
