- Аннотация: Hanford site HLW surrogates were vitrified using a cold crucible inductive melting (CCIM) technology and the aluminum-iron phosphate based materials were produced under lab scale conditions in a resistive furnace in 50 cc alumina crucibles, at small-scale unit in a -130 mm inner diameter cold crucible, and at the bench-scale facility in a 236 mm inner diameter cold crucible. Wet slurry with a water content of -50 wt.% was vitrified. Major process variables have been determined. At the bench-scale unit average slurry feeding, glass production and specific melt production rates, and melting ratio at vitrification of the slurry with -50 wt.% water content with production of aluminum-iron-phosphate glass were -1.8 kg!hr, -0.8 kg!hr, -4.2 kg/(dm2 day) and -77 kW·hr/kg of glass, respectively. The products were examined by X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy. The materials produced were found to be glass-crystalline. Magnetite- and hercinite-type spinels were present as major crystalline phases in all the samples. Orthophosphates, hematite, and zirconia-based solid solution also occurred. Ruthenium remained in oxidized form entering zirconia-based solid solution. Vitreous phase is strongly depleted with iron and enriched with sodium and aluminum.
