Samples of Y5-8-13 superconductors were synthesized by the melt process. Average criticaltemperature was about 91 K. The sample had two compounds: superconducting compounds andnon-superconducting compounds. The percentages of superconducting compounds and nonsuperconductingcompounds were 30 % and 70%. The lattice parameter of the first compound wasa=3.82912 Å, b=3.88788 Å and c=48.46370 Å. The second compound separated in two types,with percentages of 35% and 35% of Y211 (Y2BaCuO5) and BaCuO2, respectively. The Y211 had lattice parameters of a=7.21450 Å, b=12.23320 Å and c=5.62140 Å, and BaCuO2 was lattice parameter a=b=c=18.23560 Å. The melt samples reduced the non-superconducting compound,and the surface was homogenous.
