Abstract

A cosubstitution of Ca²⁺ for Y³⁺and La³⁺ for Ba²⁺ in YBa₂Cu₃O_7-δ is found to improve the corrosion resistance of this high- T_c superconductor. The reactivity characteristics of bulk and thin film samples of Y_1-zCa_zBa_2-yLa_yCu₃O _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 Y_0.6Ca_0.4Ba_1.6La_0.4Cu ₃O_6.96 with a T_c of 80 K is found to be at least 100 times more stable than YBa₂Cu₃O_6.94. Possible contributing factors that could be responsible for the marked improvement in the corrosion resistance of this high-T_c phase are discussed.
