Notes:
The transformation of high-resistivity amorphous Bi1.5 SrCaCu2 Ox to superconductive material has been characterized by structural, thermochemical, transport, and magnetic measurements. X-ray powder diffraction confirmed that rapid solidification of Bi-Sr-Ca-Cu-O melts yields amorphous materials. Differential scanning calorimetry indicated an exothermic crystallization peak at ∼455 °C with a corresponding enthalpy of ∼50 J/g. Thermal cycling of the insulating glass to a temperature above that required for crystallization results in a transformation from an insulating to a partially superconducting material with an onset temperature of 85 K.
