Dear Rob Here's good starting point in the scientific literature, offered in case you wish to pursue sol-gel processing to produce your PZT films. Nice overview: o Komarneni, Sridhar; Abothu, Isaac Robin; Rao, Alamanda V. Prasada. "Sol-gel processing of some electroceramic powders." Journal of Sol-Gel Science and Technology (1999), 15(3), 263-270. o Abothu, Isaac Robin; Ito, Yukio; Poosanaas, Patcharin; Kalpat, Sriram; Komarneni, Sridhar; Uchino, Kenji. "Sol-gel processing of piezoelectric thin films." Ferroelectrics (1999), 232(1-4), 1071-1075. Specific to PZT: o Ishimoto, Yoichi; Matsushita, Jun-ichi; Abothu, Isaac Robin; Komarneni, Sridhar. "Preparation of lead zirconate titanate using lead hydroxide by sol-gel process." Journal of Advanced Science (2000), 12(1&2), 36-37. o Abothu, I. R.; Liu, S.-F.; Komarneni, S.; Li, Q. H. "Processing of Pb(Zr0.52Ti0.48)O3 (PZT) ceramics from microwave and conventional hydrothermal powders." Materials Research Bulletin (1999), 34(9), 1411-1419. o Kalpat, Sriram; Du, X.; Abothu, Issac R.; Akiba, Akira; Goto, Hiroshi; Uchino, Kenji. "Effect of crystal orientation on dielectric properties of lead zirconium titanate thin films prepared by reactive RF-sputtering." Japanese Journal of Applied Physics, Part 1: Regular Papers, Short Notes & Review Papers (2001), 40(2A), 713-717. o Schwartz, Robert W.; Boyle, Timothy J.; Lockwood, Steven J.; Sinclair, Michael B.; Dimos, Duane; Buchheit, Catherine D. "Sol-gel processing of PZT thin films: A review of the state-of-the-art and process optimization strategies." Integr. Ferroelectr. (1995), 7(1-4), 259-77. o Hsueh, Cheng Chen; Mecartney, Martha L. "Microstructural development and electrical properties of sol-gel prepared lead zirconate-titanate thin films." J. Mater. Res. (1991), 6(10), 2208-17.
