Germanium, elemental metal fluorides

BrF and CIF ) and fused meteillle fluorides. Host elements form fluorides under the conditions that UFg Is obtained. However, only a small number of these fluorides are volatile. Hyman, et al. have published a table of some 26 elements having fluorides with boiling or sublimation points of 550 C or less. Included In this group are the fluorides of boron, silicon, phosphorus, vanadium, sulfur, tungsten, bismuth, plutonium, and the fission products, germanium, arsenic, selenium, niobium, molybdenum, ruthenium, antimony, tellurium, and Iodine. The boiling point of UFg Is 5lf.6 C. Non-volatlle fluorides from which uranium Is readily separated Include those of the alkali metals, alkaline earths, rare earths, Fe, Co, Nl, Ag, Al, Bg, )ta, Tl, Fb, Zn, Cu,...
