Amorphous samples of Bi2Sr2Ca1Cu2Ox were produced by quenching from the melt. The early-stage microstructure development in these samples was monitored using XRD, DTA, and hot-stage TEM. It was observed that the molten glass undergoes phase separation during initial quenching and that subsequent refinement of these features generates the initial DTA exotherm during heating.
