How do you propose to mitigate flourine induced stress crack corrosion in your piping? Teflon can be used in some piping but has temperature limitations. Is there an inert refractory material that could be used as a crucible for the salt melt or a lining in the plasma reduction stage? -- Jarogers2001 21:15, 13 March 2007 (PDT)

Materials

Nickel and Monel crucibles, using copper gaskets, are compatible with the fluorine gas. Teflon is appropriate for gaskets and tubing at lower temperatures. At higher temperatures, platinum crucibles would be needed, but the eutectic electrolysis should have a temperature low enough to that platinum isn't required. See J. Grannec and L. Lozano, "2: Preparative Methods", in the book Inorganic Solid Fluorides, P. Hagenmuller (ed.), Academic Press, NY, 1985, pp. 17-76. Geoffrey.landis 07:23, 14 March 2007 (PDT)
