Influence of Oxygen Micro Atmosphere During Contact Formation

Alternative Reductants for Foam Control During Vitrification of High-Iron High Level Waste (Hlw) Feeds

“…These values, while estimations, are in agreement with other studies of glasses bearing similar amounts of Fe 2 O 3 [3,15,18,41,79]. The effect of reductants on the dissolved oxygen in the borosilicate glass melt, has not been explicitly studied, however it is expected that carbonaceous materials will reduce the partial pressure of oxygen in glass melts [97][98][99]. The reductants which had the most negative oxygen balance in Table 5, namely graphite, coke and HEDTA, also had the most negative effect on the apparent oxygen fugacity.…”
