The critical current density of Bi-Sr-Ca-Cu-O superconductors of 1112 nominal composition can be improved appreciably by giving them a flash heat treatment at 1050°C for 5 minutes followed by sintering at 860°C for 18 hours. The results of XRD, TEM, magnetic susceptibility and four probe electrical measurements indicate that the grain boundary weak links are improved by this flash treatment.
