Glass optimization for vitrification of Hanford Site low-level tank waste

Structural properties of Cr2O3–Fe2O3–P2O5 glasses, Part I

“…Chromium oxide, Cr 2 O 3 , has a low solubility in many alkali alumino borosilicate glasses and typically 61 mass% [11]. However, Huang et al [12] recently reported that a simulated high-level waste containing 4 mass% of Cr 2 O 3 was easily vitrified in an iron phosphate glass at 1150°C and at 1250°C for waste loadings of 55 and 75 mass%, respectively.…”

“…The Na,O loading in the Phase 1 LAW glass for both cases is presented in Table A-17. Phase 2 LAW glass will have Na,O loading of 20 wtYo per Feng (1996). A LAW glass density of 2.65 is assumed based on the value used previously in evaluating tank waste disposal alternatives within privatization (Wojtasek 1998).…”

“…Low-level glass optimization studies (Feng et al 1996) tested sodaalumina-lime-boro-zirconia-iron-silicate systems (and subsets). for processability and durability.…”
