Abstract

The kinetics of crystallization in the Bi_xCaSrCu ₂O_w (x=1.5, 2.7) glasses prepared by twin-roller and metal-plate quenching methods have been studied by a nonisothermal method using differential scanning calorimetry. Scanning electron microscopy studies suggest surface crystallization as the dominant mechanism. The activation energy for crystal growth calculated from modified Kissinger plots assuming surface nucleation decreased with an increase in the Bi content. Such a composition dependence is consistent with that of the activation energy for viscous flow in the glass transformation range.
