Structural and transition temperature of HgPbxBa2Ca2Cu308+8 superconductor

الملخص EN

Solid stale reaction technique (SSR) was used to prepare high-Tc phase in IIgPbxBa2Ca2Cuj()ius superconductors.

The effect of additional Pb to HgBa2Ca2Cu30R-i-s was investigated.

It has been found that the maximum transition temperature TC“133K is at x=0.1.X-ray diffraction showed a tetragonal structure with an average value of c~ 15.816 A".

The average value of the valence of copper (v) is equal to 2.025.There is an increasing of density with the enhancement of the concentration of Pb
