flourine induced stress crack corrosion

New page

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? -- [[User:Jarogers2001|Jarogers2001]] 21:15, 13 March 2007 (PDT)

		+	Do we have a general page on oxygen extraction techniques? One reference I found useful as an overview was ''The Moon: Resources, Future Development, and Colonization'', by David Schrunk, Burton Sharpe, Bonnie Cooper and Madhu Thangavelu. From my review over in adb:
		+
		+	"In particular Appendix E's coverage of oxygen extraction is extremely thorough, and the authors, while finding it somewhat difficult to directly compare techniques, find 4 of the approaches worthy of considerable further research: hydrogen reduction of glass, magma electrolysis, sulfuric acid dissolution/electrolysis, and ion sputtering."

	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.
