Creators

Description

This patent describes a process for producing a superconductive complex metal oxide composition of the formula A2-xBxCOy A is a Group IIIB metal including the lanthanide series metals B is a Group IIA metal C is a metal selected from the group consisting of Cr, V, Mn, Co, Ni, and Cu and wherein O < X <1 and 2 ≤ Y ≤ 5; comprising annealing in molecular oxygen at temperatures of at least 800 degrees C. a precursor composition containing at least one bimetallic complex of A[CZ] or B[CZ] wherein Z is a ligand associated with C and where the precursor composition contains the correct stoichiometric amounts of A, B and C to yield a superconductive oxide
