Process for making high critical current density Bi2CaSr2Cu2O8 superconductor

摘要

A method for making a high critical current density Bi2CaSr2Cu2O8 superconductor includes mixing suitable solid state reactants in amounts sufficient to create a reactant mixture having a ratio of approximately 4 Bi atoms:3 Ca atoms:3 Sr atoms:4 Cu atoms and oxygen. The reactant mixture is heated to a sufficient temperature for a sufficient time to sinter the reactant mixture and form a Bi2CaSr2Cu2O8 superconductor.
