Abstract

Chemical kinetics is applied to the fatigue (stress assisted corrosion) of silica fibers in NaOH solutions. The thermodynamic parameters are determined and compared to measurements in water; the zero stress activation energy is the same for the two systems (∼25kcal/mol), but the activation volume in aqueous NaOH solutions is smaller (∼11cm3/mol) than that in water (∼27cm3/mol). The accelerated fatigue rate is dominated by a three decade decrease in the pre-exponential factor; it is shown that this decrease can be attributed to an increase in the entropy of the system.
