Corrosion of Metals and Nickel-Based Alloys in Liquid Bismuth–Lithium Alloy

Bismuth–lithium alloys are considered as primary candidates for the reductive extraction step of on-line reprocessing a molten salt reactor fuel. The corrosion behavior pure metals and nickel-based was studied in liquid Bi–Li (5 mol.%) alloy at 650 °C. tantalum, molybdenum, corrosion-resistant VDM® Alloy C-4, Hastelloy® G-35®, KhN62M, 59 were prospective materials this metal media. rates determined by gravimetric method well chemical analysis products alloy. Microstructure composition samples containing after tests evaluated using inductively coupled plasma–atomic emission spectroscopy, X-ray fluorescence analysis, scanning electron microscopy, energy dispersive spectroscopy. Metallic tantalum molybdenum do not chemically interact with alloy; rate these is only solubility medium. Ta Mo °C 0.09 0.07 mm/year, respectively. Nickel subjected to severe due dissolution nickel bismuth. Alloys type cannot be used such an environment.
