Notes:
The temperature dependence of the viscosity of metaphosphate glasses: (AgI)x(AgPO3)1−x (x=0.0–0.5) with low melting points has been determined near and below the glass transition temperature Tg using a method developed by the authors. In this temperature region, the viscosity–temperature relation of the glasses shows double Arrhenius equations, which have different activation energies near and below Tg, respectively. When an Arrhenius equation is applied to the observed α transition process near Tg for the glasses, the activation energy Eα appears to be proportional to Tg. The relation obtained for the glasses is Eα(kJ/mol)=(154±30)RTg(K) (R is gas constant). © 2000 American Institute of Physics.
