| Description |
Effect of SrO on piezoelectric, dielectric and
ferroelectric properties of (Ba1-x Srx) (Ti0.98 Zr0.02)O3,
(x = 0.00, 0.01, 0.015, 0.02 and 0.03 mol) lead free
piezoceramics was studied. The powders were prepared by
‘‘mixed oxide’’ route, calcined at 1,000 �C for 4 h. XRD
patterns of the calcined powders confirm the orthorhombic
phase. The calcined powders were de-agglomerated, pressed
into pellets and sintered at 1,150 �C for 3 h. Scanning
electron microscopy studies of thermally etched sintered
pellets show increase in the grain size with the increase in
SrO concentration. The piezoelectric charge constant
(d33 = 330 pC/N), dielectric constant (K = 2,337) and
remnant polarization (Pr = 4.69 lC/cm2) were maximum
for 0.015 mol of SrO. The temperature versus dielectric
constant graph was plotted for 0.015 mol SrO doped BZT
and the Curie temperature was found to be 116 �C.
