Abstract
Dip-coating of uniform PT, PZ and PZT films was investigated using a solution of titanium tetraisopropoxide (and/or zirconiumn-butoxide), diethanolamine, lead acetate trihydrate and isopropanol, where the diethanolamine/alkoxide molar ratioR = 1 and the water/alkoxide molar ratioW = 3. Perovskite-type PT and PZT films were obtained on glass substrates above 500 to 600 ° C when the solutions with concentrations equal to or higher than 0.4 M were used as the dip solution. The resistivity of the films formed was larger than 108 Ωcm when they were fired around 600 ° C. The dielectric constants (dielectric loss tangents) were found to be 264 (0.03) for PT, 214 (0.05) for PZT and 158 (0.02) for PZ.
