Resumen

In this work, we report the influence of processing conditions on Bi0.5Na0.5TiO3-based lead–free piezoceramics properties, obtained by conventional solid-state reaction method, employing a mechanochemical activation step and comparing two types of calcination steps. All samples were characterized by X-ray diffraction, Scanning Electron Microscopy and impedance Spectroscopy. It was observed that depending on the calcination route a secondary phase is formed. Moreover, the content of the secondary phase is strongly related to the intermediate grinding in the calcined process, and has a significant effect on the final ferroelectric properties.
