Abstract
This paper deals with the preparation of five oxalic precursors containing
lead, hafnium, titanium and niobium with Pb(1-x/2)(NH4)(2)[(HfyTi1-Y)(1-x)N
bxO(C2O4)(3)], dH(2)O as general formula [for each precursor y = 0.52 but x
takes different values (0; 0.01; 0.025; 0.05; 0.075; 0.1)]. The pyrolysis
of the complex was performed with a slow heating rate. The thermolysis lead
s to the oxides which were characterized from the microstructural point of
view (XRD) and grain size distribution. After the sintering, the ionic cond
uction properties of the material were analysed.
