Substitutional studies of nonmagnetic zinc (Zn) nanoparticles in the superconductor compound of yttrium barium copper oxide (YBa2Cu3-xZnxO7-δ) have been carried out on polycrystalline samples to determine the effect of adding zinc (Zn) nanoparticles on the stability of the unit cell structure in the presence of water. The results show that zinc (Zn) doped samples are found to degrade faster than undoped crystalline chemical compounds of yttrium barium copper oxide (YBa2Cu3O7-δ) in water and the extent of degradation increases with zinc (Zn) concentration. The results also show that there is a direct correlation between the structural instability caused by zinc (Zn) substitution at the copper Cu(2) site in copper oxide (CuO2) planes and its corrosion resistance in presence of water.
