文摘The Gibbs standard free energies of formation of the fluorides and the oxyfluorides of Y. Gd. Dy, Tb,Ho. Er and Yb were measured by using either a calcium concentration cell with Caβ' / β+x-Al_2O_3 solidelectrolyte or an oxygen concentration cell with calcia stabilized zirconia (CSZ) solid electrolyte, accordingto which the phase stability diagram of RE-O-F systems were determined.
