Fractal Dimensionalities and Microstructure Parameters of Piezoceramic PZTNB-1

The microstructure of PZTNB-1 piezoceramics (the lead zirconate-titanate solid solutions doped with sodium and bismuth) has been studied for small variation of Ti/Zr ratio near the morphotropic boundary in comparison with the tetragonal PZT-19. The size distribution of grains and porous, their shape...

Description
Summary:The microstructure of PZTNB-1 piezoceramics (the lead zirconate-titanate solid solutions doped with sodium and bismuth) has been studied for small variation of Ti/Zr ratio near the morphotropic boundary in comparison with the tetragonal PZT-19. The size distribution of grains and porous, their shape peculiarities were revealed with using computer treatment of visualized structural elements. The fractality of the microstructure were revealed and fractal dimensionalities were calculated.
