Description
Liquid nitrogen quenching of the BiSrCaCuOy superconductor is studied. The BiSrCaCuOy superconductors were obtained by initially heating them up to 860 degrees C for 48, 60 and 72 hours, respectively. These below 80 K superconductors were reheated to 860 degrees C for 16 hours and then quenched in liquid nitrogen. The zero resistivity temperatures were 82 K, 85 K and 83 K for the three heating periods. X-ray diffraction patterns indicated that these superconductors had the 2212 structure. Their response to liquid nitrogen quenching point to them being the 4424 superconductor
