Co-precipitation synthesis of precursors to bismuth-containing superconductors
Patent
·
OSTI ID:5578180
This patent describes a co-precipitation process for synthesizing precursors of a Bi-Sr-Ca-Cu-O ceramic superconducting material. It comprises forming a solution of bismuth, strontium, calcium and copper precursors in an acidic non-aqueous solvent; removing the non-aqueous solvent, thereby forming a homogeneous residue of mixed metal salts; co-precipitating the mixed metal salts from aqueous solution in the form of hydroxycarbonates such that upon calcination and heat treatment, the precursors can form a superconducting material.
