Abstracts
Pb(Zr0.53Ti0.47)O3 (PZT) was synthesized by a multiple wet dry process. Precipitates prepared from reaction
between ZrOCl2 8H2O and TiOCl2 and NH4OH in an aqueous solution was dried at 100�C, and calcined at 500�C
and 700�C. The mixture mixed with PbO and as-dried or calcined Zr0.53Ti0.47O4 (ZT) powders was calcined again at
700 and 800�C. Well crystallized ZT and PZT were formed at even 700�C. PZT piezoelectric ceramics of more
than 98.5% in a relative density was obtained by sintering at as low as 900�C.
