Abstract

Phase separation is found for the first time in quenched samples of amorphous Bi₂Sr₂Ca₁Cu₂O_x (often called "2212" composition). Clear evidemce for metastable phase separation is found using X-ray diffraction (XRD), transmission electron microscopy (TEM), and differential thermal analysis (DTA). This has serious implications for possible fabrication of high current density devices from these compositions, especially via glass-ceramic processing routes.
