Description
Summary:The paper studies the possibility of changing the properties of piezoceramic materials of various functional groups. The aim of this work was to vary the properties of piezoceramics at the stage of production by changing the technological factors with a constant chemical composition. The microstructure of piezoceramics is formed during its sintering, and also are the most important mechanical properties – density and hardness – which affect electrophysical properties. Therefore, by correcting the microstructure formation process, it is possible to change the electrophysical properties of piezoceramics. Methods of hot pressing and spark plasma sintering allow us to effectively correct the forming process of the sintered piezoceramics microstructure. The aim of this study was to use these methods for the sintering of piezoceramic materials of various functional groups and variations of their parameters. The study confirmed the effectiveness of the proposed methods for a wide-range changing piezoceramic functional parameters.
