Abstract AR
In نآلا$ paper we have reported investigations 011 the effect of simultaneous substitution of Pb at the Tl-based superconductor was prepared by adding an amount of Pb to the ٢١١.* PbxBa2CajC^09.؛, compound.
Tile usual solid-state reaction method has been applied under optimum conditions.
Bulk polycrystalline samples have been prepared by the two-step solid state reaction process.
It has been observed that the grown Tl1.xPbxBa2Ca2C.u3Oy.ؤ (with X = 0.00, 0.10 ٠ 0.20, 0.30 and 0.40) corresponds to the 1223 phase.
x-ray data of the sample showed a tetragonal structure with a liigh ratio ofTl-1223 superconducting phase.
The samples showed a transition temperatures Tc<0„wowhich were 120 K.

It was found that the change of the pb concentrations of all our samples produced a change in the density pm, c/a and volume fraction Vph(i223j.
