The effect of Li0 on the corrosion of stainless steel alloy 316L exposed to molten LiCl-Li2O-Li

Effect of Metallic Li on the Surface Chemistry of Inconel 625 Exposed to Molten LiCl-Li2O-Li

“…As described in our earlier work, XRD studies were then conducted on samples which were sealed in plastic bags in the argon atmosphere of the glove box. [10][11][12]14,15 No hydrated LiCl peaks were detected via XRD, indicating that there was insignificant moisture contamination on the samples to this point, however, peaks indicative of LiCrO 2 were observed on the samples exposed to LiCl-Li 2 O in the absence of Li (see supplemental information). Finally, sample surfaces were studied using SEM-EDS prior to methanol rinsing.…”

“…Considering the evaporation of Li and Li 2 O over time that was observed in other shortterm studies and the extended exposure periods of this study, the salt charge for each test was replaced at a period of once every 96 hours to maintain the solution chemistry. [10][11][12]14,15 To minimize the effects of impurity H 2 O, LiCl was dried in a vacuum oven in air at 200°C for 24 hours before being transferred into the glove box for storage. Additionally, the LiCl was baked for 2 hours at 550°C immediately prior to melting and subsequent addition of Li 2 O and Li.…”

“…Additionally, the LiCl was baked for 2 hours at 550°C immediately prior to melting and subsequent addition of Li 2 O and Li. 10,16 The surface analysis presented here was conducted on the samples prepared for our previous work. 1 More details on the experimental procedure and morphology of these samples can be found in that publication.…”

“…As has been shown previously, no chemical or morphological changes to the sample surface were observed to result from the methanol rinsing procedure. 10,15,18 As such, the spectra reported here were collected from the sample surfaces following removal of the salt layer due to the improved data quality afforded by the increased signal to noise ratio.…”

“…[4][5][6][7] Additionally, the studies that have been conducted have been of short duration and have shown conflicting results due to widely varying experimental conditions employed. [8][9][10][11][12][13] Consequently, this study was performed to elucidate the mechanisms responsible for material degradation in conditions applicable to the electrolytic reduction of UNF.…”
