Critical Temperature of Superconductive Transition as Influencedby Conditions of Redox Reactions Proceeding in the Oxide Systems

摘要

Analysis of critical temperature(T_c) as influencedyb the mole fraction of corresponding oxides suggests that origination of high-temperature superconductivity should be accompanied by redox reactions.The dependence of T_c on the equilibrium constants of these reactions was studied using as the model the ratos prpposed by K.B.Yatsimirskii as thermodynamic criteria of the eaction applicability inthe titrimetric analysis.The probable oscillatory character of these reactions was confirmed.In the case of cuprate systems T_c cannot exceed 150-160K.
