Abstract
By the conventional ceramic sintering method, doped lead
zirconate titanate (PZT) samples with the chemical composition
0.55PbTiO3-0.43PbZrO3-0.02[ Pb(Cd0,5W0, 5)O3] have
been obtained from oxides PbO, ZrO2, TiO2, CdO, WO3. For the
samples of A series, synthesis was led in the 1223 K temperature by 3 hours
and in the case of the samples of B series, by 6 hours in the same
temperature but in two parts (each 3 hours long). Both series were sintered
in the 1423 K temperature by 6 hours. All samples were subjected to
polarization (
K,
kV/cm,
min.) and
next dielectric (
/
, tg
properties were measured for the samples in the shape of discs. For the
samples of B series, larger values of the dielectric permittivity
/
were observed, as well as
lower values of the dielectric loss tg
