Although it is known that some of the high-Tc phases react rapidly with water, CO2, CO, and acids, no systematic comparison of the relative reactivities of the various cuprate superconductors is available. In this letter, x-ray powder diffraction, scanning electron microscopy, x-ray photoemission spectroscopy, and electrochemical measurements are utilized to establish a comprehensive comparison of the intrinsic reactivity characteristics of the common copper-oxide superconductors. Consequently, the following reactivity scale has been determined: YBa2Cu3O 7≳Tl2Ba2Ca2Cu3O 10≳Bi2Sr2CaCu2O8 ≥La1.85Sr0.15CuO4 ≳Nd 1.85Ce0.15CuO4≳Nd1.85Th 0.15CuO4.
