Abstract

The present paper reviews the current understanding of liquid-liquid immiscibility in oxide systems. The mechanism of phase separation in most oxide systems under most conditions has not yet been established. Both discrete particle and interconnected structures can be produced by either nucleation-growth-coalescence or spinodal decomposition; and the general form as well as the detailed characteristics of the phase separation structures seen in glasses depend strongly upon their composition and thermal mechanical history. Coarsening has been shown to be an important process in phase separation, and can involve changes in the morphology as well as the scale of the structure.
