Alkaline oxalate precipitation process for forming metal oxide superconductors.

摘要

Metal oxide superconductors of the yttrium-barium-copper (YBa2Cu3Oy type) type can be formed by precipitation from an aqueous solution of the salts of the metals using an oxalate precipitation reagent under basic pH conditions to form a fireable precursor only partly in the form of the oxalate salts of these metals.
