Free Energies of Formation of Ferrous and Ferric Fluoride by Electromotive Force Measurements.
NTIS: PB 250 601 :14 pages
The Bureau of Mines studied the standard free energies of formation of ferrous fluoride (fef2) and ferric fluoride (fef3) with high- temperature galvanic cells employing calcium fluoride doped with 1 mole-pct yttrium fluoride as the electrolyte. Free energies and equilibrium fluorine pressures for the two univariant equilibria of the fe-f system are tabulated and illustrated.
