Processing and properties of piezo-dielectric ceramic composites
Kučera, Ondřej ; Drdlík, Daniel (referee) ; Maca, Karel (advisor)
The diploma thesis deals with piezoelectric materials combining dielectric and piezoelectric ceramics. The first part of this diploma thesis summarizes the preparation of ceramic materials and thermodynamic of sintering. The electric properties of ceramic materials and current knowledge in BCZT ceramics are summarized. The second part of this diploma thesis describes BCZT ceramics preparation process from raw materials in powder form through the reaction of the precursors to sintering the experimental material into the compact body. The properties of prepared BCZT samples such as density, grain size, hardness, relative permittivity, piezoelectric constant and dielectric loss are summarized in the thesis.
