چکیده

Glassy materials simulating vitrified high-Na/Fe (Sludge Batch 2 – SB2) and high-Na/Fe/Al (Sludge Batch 4 – SB4) Savannah River Site high level wastes (HLW) were produced in a resistive furnace and 236 and 418 mm inner diameter cold crucibles. The effect of waste loading (WL) and glass structural factors (degree of connectedness of glass network, metal oxides to boron oxide ratios) on chemical durability of glassy materials was studied.

Structural properties of iron-phosphate glasses: spectroscopic studies and ab initio simulations.

Vitrification is the most effective method for the immobilization of hazardous waste by incorporating toxic elements into a glass structure. Iron phosphate glasses are presently being considered as matrices for the storage of radioactive waste, even of those which cannot be vitrified using conventional borosilicate waste glass. In this study, a structural model of 60P2O5-40Fe2O3 glass is propos...

Development and Testing of a Glass Waste Form for the Immobilization of Plutonium

Two alkali-tin-silicate (ATS) glasses have been prepared at Argonne National Laboratory (ANL) as part of our ongoing research in radioactive waste glass development. These glasses dissolved 5% and approximately 7% Pu. Early corrosion test results indicate that Pu-bearing ATS glass is extremely durable. The initial goal in this project concerned equally both the solubility of Pu and the durabili...

Effects of modifier additions on the thermal properties, chemical durability, oxidation state and structure of iron phosphate glasses

Modified iron phosphate glasses have been prepared with nominal molar compositions [(1−x)·(0.6P2O5– 0.4Fe2O3)]·xRySO4, where x = 0–0.5 in increments of 0.1 and R = Li, Na, K, Mg, Ca, Ba, or Pb and y = 1 or 2. In most cases the vast majority or all of the sulfate volatalizes and quarternary P2O5–Fe2O3–FeO–RyOz glasses or partially crystalline materials are formed. Here we have characterized the ...

Chemical durability of glasses obtained by vitrification of industrial wastes.

The vitrification of zinc-hydrometallurgy wastes, electric arc furnace dust (EAFD), drainage mud, and granite mud was shown to immobilize the hazardous components in these wastes. Batch compositions were prepared by mixing the wastes with glass-cullet and sand to force the final glass composition into the glass forming region of the SiO2-Fe2O3-(CaO, MgO) system. The vitrification was carried ou...

Granite like materials from hazardous wastes obtained by sintercrystallisation of glass frits

The present paper discusses sintered glass–ceramics with attractive appearance, which are obtained by vitrification of hazardous industrial wastes. The chemical durability of parent wastes and resulting glasses was characterised by toxic characteristics leaching procedure (TCLP). The crystallisation behaviour was evaluated by DTA and XRD, while the structure of materials was observed by optical...
