The enhancement of superconductor compounds contribute in reducing the heat pollution
that gain from electric transfer. The main focus of all researchers pointed on high temperature
superconductors where they aim to get higher critical temperature. This research focus on investigations the
concurrent substitution effect Yttrium at the Barium site of HgBa2Ca2Cu3O8+δ superconductor for x=0, 0.1, 0.2
and 0.3, The samples were prepared using a solid-state reaction technique and all samples were exposed to
XRD so as to know the crystal structure and its lattice constants. XRD data collected from different samples
showed that represents high critical phase and the analysis presents a tetragonal structure. To find the critical
temperature 4 probe technique was adopted using relationship electrical resistance and temperature. It was
observed that there was a critical temperature rise with the increase of strontium from 95 K to 120 K.
