Abstract

The first measurements in any system of the effects of multi-step annealing treatments on the composition/time-dependent nucleation rates are presented for Na₂O·2CaO·3SiO₂ glasses made near the stoichiometric composition. The experimental results compare well with the time-dependent behavior predicted from the classical theory of nucleation, though small systematic differences suggest possible deviations from the kinetic model. These studies support an earlier claim that the composition dependence of nucleation in this glass is dominated by changes in the crystal-glass interfacial energy.
