摘要：
The techniques of scanning electron microscopy, energy dispersive X-ray microanalysis, and dark-field transmission electron microscopy were combined to study the phase stability of CdF//2-LiF-AlF//2-PbF//2 glasses. The selected compositions, presumed to be exceptionally stable exhibited a liquid-liquid immiscibility phase transition; this led to the formation of two amorphous phases consisting of a matrix near the original glass composition and an isolated spherical phase which was richer in CdF//2 and poorer in PbF//2 than the matrix.
