Title: Liquidus Temperature Measurements for Modeling Oxide Glass Systems Relevant to Nuclear Waste Vitrification

Abstract

Liquidus temperatures TL have been measured and primary phases have been determined for 42 (from an initial test matrix of 60) compositions within the Al2O3-B2O3-CaO-Na2O-SiO2 glass forming network. These data have been used to test TL calculations and primary phase predictions obtained using a modified associate species model (ASM). This paper highlights the strong linear correlations between composition and TL for glasses within the same primary phase fields, the strengths of the ASM in determining TL and phase for glasses observed to precipitate nepheline, and weaknesses of the ASM in predicting phase information and TL for calcia- and boria-rich glasses. TL has also been measured for glasses using two baseline compositions from the five-component network that have been individually doped with Fe2O3, Li2O, NiO, ZrO2, Cr2O3, ZnO, and MnO. These additional oxide glasses are intended for use as benchmark data for testing the model as more oxides are included.

  • Borosilicate glasses will be used in the USA and in Europe to immobilize radioactive high level liquid wastes (HLLW) for ultimate geologic disposal. Process and product quality models based on glass composition simplify the fabrication of the borosilicate glass while ensuring glass processability and quality. The process model for glass viscosity is based on a relationship between the glass composition and its structural polymerization. The relationship between glass viscosity and electrical resistivity is also shown to relate to glass polymerization. The process model for glass liquidus temperature calculates the solubility of the liquidus phases based on the free energies ofmore » formation of the precipitating species. The durability product quality model is based on the calculation of the thermodynamic hydration free energy from the glass composition.« less

  • Cold-cap reactions are multiple overlapping reactions that occur in the waste-glass melter during the vitrification process when the melter feed is being converted to molten glass. In this study, we used differential scanning calorimetry (DSC) to investigate cold-cap reactions in a high-alumina high-level waste melter feed. To separate the reaction heat from both sensible heat and experimental instability, we employed the run/rerun method, which enabled us to define the degree of conversion based on the reaction heat and to estimate the heat capacity of the reacting feed. Assuming that the reactions are nearly independent and can be approximated by themore » nth order kinetics, we obtained the kinetic parameters using the Kissinger method combined with least squares analysis. The resulting mathematical simulation of the cold-cap reactions provides a key element for the development of an advanced cold-cap model.« less

  • Spinel crystals precipitate in high-level waste glasses containing Fe, Cr, Ni , Mn, Zn, and Ru. The liquidus temperature (TL) of spinel as the primary crystallization phase is a function of glass composition and the spinel solubility (c0) is a function of both glass composition and temperature (T). Previously reported models of TL as a function of composition are based on TL measured directly, which requires laborious experimental procedures. Viewing the curve of c0 versus T as the liquidus line allows a significant broadening of the composition region for model fitting. This paper estimates TL as a function of compositionmore » based on c0 data obtained with the X-ray diffraction technique.« less
