Dynamical Scaling in the Glass System B2O3-PbO-Al2O3

Abstract

An experimental small-angle x-ray scattering study of a phase-separating quasibinary glass ${\mathrm{B}}_2$ ${\mathrm{O}}_3$-PbO(${\mathrm{Al}}_2$ ${\mathrm{O}}_3$) is compared with the predictions of nonlinear theories for advanced stages of decomposition. The time evolution of the moments and the scaling of the structure function show a reasonable agreement, suggesting the validity of the scaling hypothesis in glassy systems.
