摘要：

An aqueous, metallo-organic precursor for PbTiO3 (PT), Pb(Zr, Ti)O3 (PZT), and (Pb1-x, La(x)) (Zr(y), Ti1-y)1-x/4O-3 (PLZT) ceramic powders has been developed employing the acetate complexes of Pb2+, La3+, Zr4+, and Ti4+. The crystallization behavior (e.g., degree of crystallization and crystallite size) was examined over the temperature range of 400-700-degrees-C with concentrations of excess lead varying from 0-5% using x-ray diffraction (XRD) and Fourier transform infrared (Ff IR) spectroscopy techniques. It was found that PT, PZT, and PLZT crystallize at temperatures as low as 450-degrees-C, 500-degrees-C, and 500-degrees-C, respectively, and the excess lead required for crystallization of the perovskite phase is less-than-or-equal-to 1%. Intermolecular mixing among acetate precursors via chelating and bridging structures was evident and appeared to be responsible for the low crystallization temperatures. The process is compared to the current sol-gel methods for its possible use in thin film ferroelectric manufacture.
