Abstract

This study concerns the fabrication of a `soft' lead zirconate titanate (PZT) thick films on a Platinum substrate (5 X 15 mm size, 0.25 mm thickness) by the screen printing method. Various parameters connected with the screen printing (rheological characteristic of the ink, firing conditions of the layer) as well as those concerning the active powder used (grain size, grain distribution) are studied. The screen printed specimens characterized from their dielectric properties and their hysteresis loop show a diminution compared to the bulk ceramic, which may be attributed to the less than completely densified films. A study of the displacement versus an a.c. electric field of the piezoelectric film on a platinum substrate is also achieved by a laser doppler vibrometry technique. A comparison with a machined down ceramic pasted on this same Pt substrate is carried out.
