Abstract:
Phase separation in glass systems has been studied since the turn of the century, and has developed commercial interest with the VYCOR process and recent interest in glass-ceramics. Phase separation has been studied in the lead borate glass system because it is known to separate across a fairly wide compositional range, and has been shown to undergo both stable and metastable phase separation. To further understand immiscibility in the lead borate system, an investigation has been performed to determine the immiscibility gap under nearly equilibrium conditions. Small-angle x-ray scattering (SAXS) has also been used in an attempt to characterize the kinetics of phase separation of a high-lead composition in the metastable region, using novel sample preparation methods.
