Abstract

The obtention of iron aluminium silicate- phosphate glasses including U3O8 oxide has been carried out and the study of crystalline phases formation. A serie of these original glasses have been investigated by thermal cycles at 780? C for promoting the nucleation and growth of crystalline phases of iron aluminium phosphates including U3O8 in the 5.1- 13.71 wt% range. Thermal expansion and DTA/G analysis have been carried out showing behaviour trend to crystallization of these glasses. The glass with higher uranium oxide content shows liquid phase in phase separation which change of microstructure during HREM observations. It seems produced a pulsed order- disorder processing which takes place under the electron beam. This effect first observed in TEM-HREM on phase separation droplets is discussed.
