The microstructure of heavy‐metal fluoride glass of composition 28.SCdF 2 ·5.0LiF·28.5AlF 3 ·38PbF 2 was investigated using scanning electron microscopy and energy‐dispersive X‐ray techniques. Liquid‐liquid phase separation was observed in crucible‐cooled glass samples. The volume fraction of the dispersed glass phase increased substantially as a result of heating the sample at 309°C for 1 h.
