Abstract
A method for making a high critical current density Bi.sub.2 CaSr.sub.2 Cu.sub.2 O.sub.8 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 Bi.sub.2 CaSr.sub.2 Cu.sub.2 O.sub.8 superconductor.
