摘要：

An experimental study of the origin of elastic, dielectric, and piezoelectric losses in ceramic-matrix piezocomposites PZT/alpha-Al2O3 with different volume concentrations and particle sizes of alpha-Al2O3 microcrystalline filler was performed. The microstructural features and concentration dependences of the imaginary and real parts of the complex elastic, dielectric, and piezoelectric characteristics of composite piezoelectric elements were studied. The analysis of the obtained dependences was carried out and a physical interpretation of the obtained results was proposed.
