摘要：

The glass transition of B2O3 is characterized on time scales ranging from about 10(3) to 10(6) s by continuous measurements of the volume expansion upon cooling and heating. The data show a linear relationship between the glass transition temperature and the logarithm of the heating or cooling rate. The hysteresis of the volume at the glass transition becomes narrower at lower rates. The data are compared to two models for the nonequilibrium kinetics at the glass transition.
