摘要：

In this work, complex studies of the elastic dispersion and losses in porous piezoceramics based on solid solutions of the PZT system were carried out. Full set of complex constants of porous ceramics with different porosity and their frequency dependences were measured using the piezoelectric resonance analysis method.The microstructural and physical mechanisms of elastic losses and dispersion in porous piezoceramics were considered.
