Thermodynamics of Interaction of Rare-Earth Metals with d-Metals. The Scandium ― Iron System
Tóm tắt
Gibbs free energies, enthalpies, and entropies of formation of the compounds ScFe2 and Sc29Fe6 are found by measuring the emf of galvanic cells in the range 720-1030 K. The nature of interaction in Fe ― REM binary systems is analyzed. Scandium is shown to behave like a 3d-metal during interaction with iron.
