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.
