Abstract

A cosubstitution of Ca2+ for Y3+and La3+ for Ba2+ in YBa2Cu3O7-δ is found to improve the corrosion resistance of this high-Tc superconductor. The reactivity characteristics of bulk and thin film samples of Y1-zCazBa2-yLayCu3O 7-δ indicate that the corrosion resistance in water environments increases with increasing degree of cation substitution up to z=y=0.4. The composition of Y0.6Ca0.4Ba1.6La0.4Cu 3O6.96 with a Tc of 80 K is found to be at least 100 times more stable than YBa2Cu3O6.94. Possible contributing factors that could be responsible for the marked improvement in the corrosion resistance of this high-Tc phase are discussed. © 1995 American Institute of Physics.
