Piezoelectric materials consisting of Pb(Zr/sub x/Ti/sub 1-x/) O/sub 3/ (x=0.52 and 0.94) and glass powder 4PbO-B/sub 2/O/sub 3/ were studied. It is shown that, if a small amount of 4PbO-B/sub 2/O/sub 3/ glass powder is added to the PZT system, the sintering temperature can be reduced and the dielectric and piezoelectric properties will be enhanced. For PZT (52/48) doped with 0.2 wt.% 4PbO-B/sub 2/O/sub 3/ and sintered at 1150 degrees C for 30 h, the planar coupling factor k/sub p/ is higher than that of plain PZT (52/48). For PZT (94/6) doped with 0.5 wt.% 4PbO-B/sub 2/O/sub 3/, a planar coupling factor and a dielectric constant equal to 0.16 and 330, respectively, can be attained with sintering at 950 degrees C for 30 h.
