Paper Title:
Mechanical and Electrical Properties of Pb(Zr,Ti)O3 Ceramics Prepared by Aerosol Deposition
  Abstract

Full-dense bulk Pb(Zr,Ti)O3 (PZT) ceramics with various grain sizes were prepared by aerosol deposition (AD) employing various firing temperature from 800 to 1200°C. It was confirmed that the Hall-Petch relationship is obeyed in AD-processed PZT ceramics over the almost whole grain size range, which is indicating that only grain size could be the determining factor of hardness in AD since density is almost constant against the grain size. As compared with conventional sintering technique, AD-processed PZT ceramics exhibited higher hardness and higher or at least equivalent electrical properties over the whole grain size range investigated, which is indicating that the piezoelectric ceramics with improved mechanical properties can be realized by AD without any sacrifice in electrical properties.
