The aim of this research is to study the effect of yttrium substitution on the pure phases superconductor HgBa2Can-1CunO2n+2+ (n=1 & n=2). The solid state reaction method was used to prepare the samples in this work, followed firstly by the x-ray examination. The results of the XRD diffraction analysis showed that the structure for pure and doped phases was tetragonal. The change of yttrium concentration effects of all samples on the lattice parameters, electrical resistivity, the hardness, and the critical temperature Tc. The ratio of x=0.25 for n=2 gave the highest Tc. The results of the dielectric constant showed increasing with the Y addition increase for both phases (1 and 2) for high and low frequencies. While the hardness results showed a decrease in its values with Y addition increasing.
