Abstract : A machinable high Tc ceramic superconductor is formed by weighing and mixing appropriate stoichiometric amounts of Bi2O3, SrCO3, CaCO3, and CuO (BSCCO), removing carbonates from the mixture, melting the mixture, casting the melted mixture into a mold, and inducing superconductivity and growth of randomly oriented platelets in the cast.
