Effect of feed melting, temperature history, and minor component addition on spinel crystallization in high-level waste glass

Abstract

Spinel crystallization affects the anticipated cost and risk of high-level waste (HLW) vitrification. Spinel, (Fe,Ni) (Fe,Cr)2O4, is the primary crystalline phase that precipitates from melts containing Fe and Ni in sufficient concentrations. This study was undertaken to help design and verify mathematical models for a HLW glass melter in which spinel crystals precipitate and partially settle.
